China has more solid-state battery patents than anyone else and still fears being left behind for one reason: Japan

by

What China is leading the energy and mobility transition What we are witnessing does not take anyone by surprise at this point. However, not all fish are sold, and in energy storage we are going to witness a significant evolution with the arrival of solid state batteriesa type of battery that we have been talking about for years. Just like they count From CarNewsChina, the country dominates the volume of research and records on solid-state batteries, but be careful because that leadership on paper does not guarantee winning the commercial race. And it is that a new analysis of the Xinhua agency recognizes that the United States, Europe, Japan and South Korea are moving forward with more industrial coordination and better international deployment of patents, just when the technology enters a decisive phase for its commercialization. Why it matters. Solid-state batteries are considered the next big leap from current lithium-ion batteries. These promise more energy density, faster charges, greater security and longer lifespan. They not only affect the electric car, but also humanoid robotseVTOL (vertical take-off aircraft), consumer electronics and stationary storage. Basically, whoever controls the technology and, above all, its manufacturing at scale, will set the pace of mobility and energy in the next decade. Patent war. China accounts for around 35% of the world market for solid-state patents and 39% of those related to electrolytes, the largest global share, according to share from CarNewsChina. Scientific publications have gone from 21 articles in 2015 to 562 in 2023, with institutions such as the Chinese Academy of Sciences or Tsinghua University leading advances in the engineering of the solid-solid interface, which for years has been one of the great bottlenecks. On the other hand, Japan continues to be the leading technological source with about 37% of global requests, compared to 30% from China. Japan is ahead. The problem in China is not quantity, but the concentration and quality of your strategy. Among the 30 most relevant institutions in the world in solid state and electrolyte patents, 17 are Japanese7 Chinese, 5 South Korean and only 1 European. The top ten positions are entirely Japanese or Korean. Toyota, alone, accumulates around 40% of all intellectual property in the sector. Added to this is a structural weakness, since Chinese companies register many fewer international patents than their Japanese and South Korean rivals, who shield their technology in the United States, Europe, India and Southeast Asia. The companies that move the board. CATL, BYD and SVOLT are leading the latest phase of this technology. And only in 2023 will Chinese companies filed more than 500 patent applications. Gotion High-tech The design of a 2 GWh line for totally solid batteries has already been finalized and another 0.2 GWh pilot line is operating with tests on vehicles. Ganfeng Lithium, backed by Changan, claims to have reached 1,100 cycles in a 400 Wh/kg cell and aims for 500 Wh/kg in production. On the other hand, Chinese researchers have also shown a prototype of 451.5 Wh/kg capable of charging in three minutes. CATL, for its part, is patenting lithium compounds with fluorine and sulfur electrolytes to improve fast charging and thermal stability. Deadlines. own report Xinhua places the start of production in small series around 2027 and broader commercialization around 2030. The industry continues to work in parallel on three electrolyte routes (sulfide, oxide and polymer) without any having won yet. Furthermore, according to the media, there are still challenges to overcome, including the formation of lithium dendrites, ionic transport mechanisms, solid-solid interface engineering or cell failure modes. And now what. China is preparing to industrialize what it currently masters in the laboratory. And its first national standard on solid state batteries (“Terms and Classification”) is under public consultation and proposes to differentiate between liquid, solid-liquid hybrid and totally solid cells. For now, the country dominates in terms of volume of papers and research, but it is clear that real dominance will come from manufacturers who first resolve large-scale production, cost, durability and safety. And let’s be honest, China has an advantage, especially with CATL and BYD controlling much of the world’s battery sharebut in the field of solid-state batteries there is still play.

Six phones that already have a silicon-carbon battery and promise up to three days of use without being a brick

by

The silicon-carbon batteries They are no longer theoretical or a thing of the future: they are here to stay. At the moment, it is the Chinese manufacturers that are betting on this technology, but it is normal that we will soon see mobile phones of all types with these batteries. And the most striking thing is that this technology is not reserved only for the high-end: There are options for less than 400 euros. Let’s first see what this technology consists of and what differences there are with lithium-ion batteries. Oppo Find X9 5G 16GB/512GB Black The price could vary. We earn commission from these links Carbon-silicon as one more detail to look at when choosing a mobile Although many aspects come into play, as a general rule, the greater the battery capacity, the greater the autonomy of a device. The “problem” is that the batteries that cell phones (and other devices) have been using until now, lithium ion onesuse graphite anodes, which has already reached its energy density ceiling. In other words: for one of these batteries to have more capacity, it has to be bigger. And that causes the device that uses it to become a hulk. This is why silicon-carbon is so important. These batteries, which use this material in the anode instead of graphite, can store much more energy without the need to increase the size of the battery. This means that we can have telephones with a thickness less than 8 millimeters with batteries that exceed 6,000 mAh. Just a year ago it was unthinkable; Today it is beginning to be an accessible reality. Small note here to keep in mind. If you start searching on the Internet for a mobile phone with silicon-carbon, you may find versions with different capacities. Example: the Vivo X300 Pro has an international version with a 6,510 mAh battery, while in Spain it has arrived with 5,440 mAh. Because? As our colleague explains Ivan Linaresit all boils down to saving costs, but not manufacturing costs, but transportation. For safety reasons, if batteries exceed a certain nominal capacity (UN3481 regulations speaks of 20 Wh for each cell), transporting the device becomes much more expensive. Three mobile phones with silicon-carbon batteries for less than 500 euros As we mentioned above, despite being a relatively new technology, silicon-carbon is not limited to very expensive mobile phones. It is true that manufacturers like Samsung, Google or Apple still do not use these batteries, but we have several Chinese manufacturers that do. Below, we leave you three examples that cost less than 500 euros right now. Xiaomi Redmi Note 15 Pro+ The cheapest option on this list is Xiaomi’s Redmi Note 15 Pro+ 5Ga device that is currently coming out 300.29 euros with the coupon ‘ESCD18’. It has a 6,500 mAh battery with a thickness of 8.47 millimeters, with enough autonomy for more than two days. It is not the most powerful option nor the one with the best camera, but it does have good fast charging (100 W), a 6.83-inch screen compatible with Dolby Vision and a speaker system that works well. XIAOMI REDMI Note 15 Pro+ 5G – 8+256GB Smartphone, 6.83″ 1.5K AMOLED Screen, Snapdragon 7s Gen 4, 200 MP Camera, 100W Hypercharge, Charger Not Included, Mocha Coffee (ES Version) The price could vary. We earn commission from these links POCO X8 Pro Max There are batteries with a lot of capacity on this list, but not as much as the one included in the POCO X8 Pro Max. It is impressive that a mobile phone that is 8.2 millimeters and weighs 218 grams has an 8,500 mAh battery, figures more typical of a tablet than a mobile phone. As we always say, it depends on the use we give it, but it is a capacity that will easily give you between two and three days of autonomy. In addition, it performs remarkably and has a good 6.83-inch screen. Costs 412.79 euros with the coupon ‘ESCD18’. Xiaomi POCO X8 Pro Max (12+256 GB) The price could vary. We earn commission from these links Realme 16 Pro+ 7,000 mAh battery in a thickness of 8.1 millimeters. That’s what this one has Realme 16 Pro+a device that has a telephoto sensor that is not present in the two previous options. Beyond this, it also offers good performance and a 6.8-inch screen that stands out for having a sustained brightness level of 1,800 nits. Translation: we will be able to see it perfectly even on those very sunny days. comes out for 361.24 euros with the coupon ‘ESCD18’. realme 16 Pro+ 5G Smartphone 8+256GB, 6.8 Inch Screen, Master Grey, 144Hz, 80W Ultra Charge, 7000mAh Battery, 300MP Camera, Snapdragon 7 Gen 4, IP69 The price could vary.

Three mobile phones with silicon-carbon batteries for more than 500 euros If you are looking for mid-range or high-end mobile phones with silicon-carbon, you have a choice. There are very outstanding options that have just come out, such as the Vivo X300 Ultra either the Oppo Find X9 Ultrabut we are going to give you three options that are very interesting and that, since they have been available for a little longer, we can find something cheaper. Vivo X200 FE He Vivo X200 FE It is the mobile phone on this list that has been available the longest, hence we can find it at a very attractive price (582.79 euros with the coupon ‘ESCD18’). In this case, we have a device with a 6,500 mAh battery and 90 W fast charging, which is not bad at all. This device is highly recommended if you like compact mobile phones, since it is less than 8 millimeters thick (7.99 specifically) and has a 6.31-inch screen. Mobile – vivo The price could vary.

If you were waiting for the moment to make the jump to a high-end mobile phone, now is a good time to do it thanks to this offer that Amazon has. He Xiaomi 17 (the latest flagship launched by the Chinese manufacturer) has dropped in price and has gone from costing 1,099.90 euros to 899.99 euros. Although yes, it is a flash offer, so it will be available for a limited time. XIAOMI 17 – 12+512GB Smartphone The price could vary. We earn commission from these links A mobile phone with a Snapdragon 8 Elite Gen 5 processor that offers plenty of power The heart of this Xiaomi 17 is he Snapdragon 8 Elite Gen 5 (accompanied by 12 GB RAM and 512 GB of internal storage). In addition to being 30% faster than its predecessor, it has made a giant leap in thermal efficiency thanks to the 3D IceLoop system. Although it is true that his older brother (the Xiaomi 17 Ultra) takes the 200 MP sensor, this standard Xiaomi 17 is not far behind. Incorporates a 50 MP main camera with a one-inch sensor and refined with LOFIC HDR technology, to control high lights in night scenes. Another of its surprising features is its battery. This has a capacity of 6,330 mAh, a capacity which is surprising in a body of just 8 mm. In addition, it supports fast charging at 100 W, so it is perfect if you want to charge your phone in the morning, while you have breakfast, before going to work. In real practice, it is a mobile phone that lasts a day and a half perfectly without going through the plug. If you want a compact high-end mobile (its screen is 6.3 inches), flat and extremely powerful, this Xiaomi is a good purchase option. In this new Xiaomi 17 family, you could say that this terminal has stopped being the “little brother” to become a very balanced option for the general public. ⚡ IN SUMMARY: offer for the xiaomi 17 today ✅ THE BEST Leica cameras: The Xiaomi 17 takes photos with organic texture and dynamic range (thanks to the LOFIC sensor) that look like they were taken from a professional camera rather than a smartphone. Battery: It seems like magic to integrate 6,330 mAh in such a thin design. In addition, its autonomy is enough for a full day (and then some). ❌ THE WORST The price… Xiaomi is no longer the affordable mobile phone brand that we were used to. This terminal fully enters the 1,000 euro barrier, competing head to head with Samsung and Apple. Secondary cameras… Although the main lens is superb, the wide-angle lens can be a step behind in low light situations, making the jump in quality between sensors noticeable. 💡 BUY IT IF… You are an avid photographer and value the natural color and manual control that Leica optics offer. ⛔ DON’T BUY IT IF… Your budget is tight, since a Xiaomi T series or a high-end Poco can give you a similar (although not the same) experience at 70-80% but at half the price.

Charging the battery properly is a hassle. So the Madrid firefighters have had to come out and explain how to do it.

by

The Madrid Security and Emergency Agency has published a series of recommendations (something that comes remembering year after year) as a result of something they see constantly (: domestic accidents due to bad practices when charging a phone. What in 2026 seems obvious does not have to be so obvious, so it is worth collecting some of the points in which some users continue to fail. It doesn’t work anywhere. Raise your hand if you have ever carried your cell phone on the bed or sofa. Such a common practice can end up leading to a fire. The basic recommendations are clear. Do not charge the device near any device that emits heat, such as the car dashboard itself (when it is connected by cable to it) or a radiator. Do not carry it on beds, chairs or textile surfaces. These, in addition to increasing the temperature of the device, are highly flammable. The 112 recommendation is the same that we have been doing for years at Xataka: charge on a smooth, non-combustible surface, and if possible cool and ventilated. Be careful with chargers. 112 explains that we should only use “approved chargers.” To verify that this is the case, all we have to do is look at whether or not the charger has a visible CE marking. This type of charger always includes data on its input voltage, output, amperage and power. As Xatakero advice, we recommend buy chargers with official fast charging protocols such as Quick Charge (QC), Power Delivery or PPS. This is a perfect indication that the manufacturer has taken care to offer compatibility with the best charging protocols of the moment, since the final power does not tell us everything: how it charges matters. Add to this that, although chargers are specifically designed to collect heat (all the heat they collect is heat they take away from your device), it is best not to put them near flammable surfaces. Be careful with repairs. A point that we do not usually take into account and that can end in a bad outcome is the quality of the replacement battery. Nowadays it is more than common to use compatible batteries instead of the original ones, since they are much cheaper. Here it is important to be clear about where the battery comes from and what its safety guarantees are. A poor quality battery can bloat, not control the temperature like an original one, and cause significant damage. Go deeper. It is no coincidence that year after year, and with the arrival of heat, you discover these articles with tips (that you may or may not know) on how to charge your cell phone. Fires caused by plugged-in electronic devices remain on the order of the dayand every memory about the recommendations for charging our devices makes sense. With the rise of silicon-carbonincreasingly larger batteries, and fast charging systems that exceed 100w, we have advanced and safe technology, but it requires a little effort on our part.

a battery that charges in six minutes

by

CATL, literally the largest Chinese battery company in the world, has just presented its new technologies at its Tech Day, and has left us some very interesting gems, including its new ultra-fast charging batteries. And the manufacturer has managed to develop a battery capable of charging the car in just over six minuteswith an autonomy that far exceeds current limits. The Achilles heel of the electric. The biggest psychological barrier for anyone considering buying an electric car remains the same: how long it takes to charge and how far it goes on a charge. CATL has been trying to eliminate this problem at its roots through innovation for years. What it has presented now has possibly been the biggest leap that the company has taken on both fronts at the same time. What you have presented. The company has announced two technologies main. The first is the third generation of its Shenxing battery, made of chemical LFP (lithium-ferrophosphate), which manages to charge from 10% to 98% in 6 minutes and 27 seconds. In just 3 minutes and 44 seconds it reaches 80%. The company claims that even at temperatures of -30°C, the battery can be charged from 20% to 98% in just 9 minutes. The key to these magnificent figures is the world’s lowest internal resistance for ultra-fast charging: 0.25 milliohms, half the industry average. On the other hand, there is the new version of its Qilin condensed battery, aimed at long-haul vehicles, which reaches 1,500 kilometers of autonomy on a single charge, according to affirms the company. That is more or less equivalent to going from Madrid to Paris without recharging, and on paper you would still have autonomy. The previous version reached 1,000 km. How is it compared to BYD. CATL’s main rival in the global electric vehicle battery market is BYD, and there is so much competition between both companies that they are pushing the pace of innovation to an unprecedented level. Just a few days ago we were in Paris at the European presentation of Denza, where BYD showed the capabilities of its Blade Battery 2.0capable of charging from 10% to 97% in 9 minutes. On paper, CATL’s new Shenxing improves that time significantly, achieving practically the same load in just over 6 minutes. In extreme cold conditions, the difference is also in favor of CATL: 9 minutes compared to the 12 minutes needed by the BYD system for similar loads at -30 °C. But hey, regardless of the manufacturer, the truth is that the figures being achieved today are quite spectacular. Together, both companies control more than half of the global electric car battery market. According to data From SNE Research, CATL closed 2025 with 39.2% of the global market, while BYD occupied second place with 16.4%. Other technologies. CATL has also announced relevant developments on other fronts. presented the second generation of its Freevoy hybrid battery, which mixes LFP and NCM chemistry at the powder level for extended range hybrid vehicles (EREV). This battery allows up to 600 km of pure electric range with ultra-fast charging as standard. By the end of this year, in addition, the company has promised to begin mass production of sodium-ion batteries, a technology that reduces dependence on lithium, cobalt and nickel. Charging points. In infrastructure, which is perhaps the part that most interests the consumer, CATL has announced which will build 100,000 battery charging and changing points in China before the end of 2028, in collaboration with several car manufacturers in the country. As usual, in Europe we have to wait. Mass adoption and infrastructure is one of the fundamental steps for the end customer to opt for an electric vehicle. In Spain we have plenty of charging pointsbut according to latest Anfac barometeronly 4% of the available charging points reach 250 kW of power or more, the threshold necessary to access this type of ultra-fast charging. In fact, BYD needs 1,500 kW of power, and they plan to bring about 3,000 points in Europe by 2026. So yes, there is still some way to go in this.

the largest battery company in the world is no longer just about batteries

by

The Chinese company specialized in the development of batteries has published results for the first quarter of 2026 that have left analysts speechless. Not because they are good, but because no one saw them coming. And the income has exceeded the forecasts of several analysis firms by 40%. The margin of error is so large that it only shows the obvious: that CATL It has long ceased to be just a battery company. What the numbers say. In the first quarter of 2026, CATL had a turnover of 129.1 billion yuan (about $18.9 billion), 52.5% more than in the same period of the previous year, according to they count from Reuters. Net profit grew 48.5% to 20.7 billion yuan. Analysts expected revenue growth of 35.7% and profit growth of 20.9%. The reality is that the numbers almost double the estimates. If the context of the successful year they had in 2025 is added, the image is just as groundbreaking, since according to the annual report The company’s own revenue that year reached 423.7 billion yuan, with a growth of 17%, and net profit rose 42%. Why analysts They have failed so much. Market consensus continued to treat CATL as a supplier of cells for electric cars. The problem is that this approach ignores two movements that are redefining the company. The first: energy storage, a business with higher margins than vehicle batteries, already represented around a quarter of the product the company shipped in the first quarter. According to data Production data collected by Hello China Tech, in April storage had climbed to 41.3% of total cell production, up from less than 20% a year earlier. The second movement: internationalization. Approximately a third of CATL’s revenue already comes from outside China. A Bet that explains everything. Energy storage is not a segment that CATL has joined by inertia. It is the logical consequence of a thesis: the world needs to store renewable energy on a massive scale. The war in Iran has skyrocketed global energy costs and accelerated demand for renewables, making storage systems critical infrastructure. CATL, which already led that market with a global share of 30.4% in 2025, according to SNE Research (for the fifth consecutive year), has arrived at the exact moment with the necessary capacity. And its shipments of batteries for storage have grown by 80% year-on-year in 2025. Europe as a lever for internationalization. The Debrecen plant, in Hungary, went into mass production during the first quarter of 2026. An investment of 7.3 billion euros to supply Mercedes-Benz, BMW, Stellantis and Volkswagen, with a planned capacity of 100 gigawatt-hours annually and a planned workforce of 9,000 people. This factory is proof that CATL is not content with being a supplier that exports cells, but rather a manufacturer with an industrial presence in the markets it serves. At home, dominating like never before. At the same time, CATL has reached a milestone in China that it had not achieved for five years. According to data from the Chinese Passenger Car Association collected According to CarNewsChina, its production share of electric vehicle batteries in the domestic market exceeded 50% in the first quarter of 2026. In the NMC (nickel-manganese-cobalt) type battery segment, that share reaches 81.6%. And in the LFP (lithium-iron-phosphate) segment, where there is more competition, it reaches 41%, the highest level in four years. The world’s second largest manufacturer, BYD, fell to 13.4% global share, from 16% a year earlier. What CATL is today, beyond batteries. The company itself has been trying to change the story for some time. In your 2025 annual reportstates its ambition to become “a leading global zero-carbon technology company.” It may sound like corporate rhetoric, but it is worth noting that CATL has storage systems deployed in nearly 2,300 projects around the world. Its batteries power artificial intelligence data centers, including SenseTime’s in Shanghai, which the company says reduces electricity consumption by more than 10 million kilowatt-hours annually. It also has subsidiaries in the electric aviation sector and solutions for maritime transport zero emissions. It operates more than 1,000 battery exchange stations for passenger cars and more than 300 for heavy trucks. And it is building what it describes as the world’s first zero-carbon off-grid industrial park, in Shandong. ANDThe market has not yet it has finished processing. It’s not all good news. Morningstar analyst Vincent Sun warns that the automakers’ strategy of diversifying suppliers and cutting costs could “dilute CATL’s pricing power and put pressure on its unit profit.” When you are the dominant supplier, customers have incentives to reduce their dependence. Here it would be necessary to see if CATL’s diversification towards storage, energy services and internationalization builds a sufficient barrier.

CATL is the largest battery manufacturer in the world and has a new goal: electrify the entire sea

by

CATL, the Chinese giant that dominates the global battery market for electric vehicles, it has become entrenched to move towards a new front: the electrification of maritime transport. It makes more sense than it seems, but it is still a great technical challenge. Although the company is not caught by surprise. Below these lines we tell you all the details. What you are already doing. The company, which controls 37% of the global market for batteries for electric cars and 22% of the energy storage market in electrical networks and data centers, has been working in the naval sector since 2017. It has so far deployed its battery systems on about 900 vessels, although mainly on small ships operating near the Chinese coast, in ports or on rivers. Its subsidiary dedicated specifically to powering ships already exists, and this year it plans to more than double the team’s staff, reaching around 500 people, according to confirmed Su Yi, the head of that division, told the Financial Times. Why now. As the media shares, the maritime sector is responsible for 3% of global carbon emissions, and the International Maritime Organization has set itself a goal halve those emissions by 2050. But there is another more recent catalyst that has made many companies reconsider: the recent escalation of war between the United States and Israel against Iran and the temporary closure of the Strait of Hormuz. The war in the Middle East has once again highlighted the fragility of energy supply chains and CATL has a good margin of maneuver there. According to counted To FT Neil Beveridge, an analyst at Bernstein specializing in energy in China, the long-term consequence of this type of situation will be an acceleration of the “global mega-migrant towards electrification.” CATL shares on the Shenzhen stock exchange have risen about 13% since the conflict with Iran broke out. The challenges. Electrifying boats is not like electrifying cars, up to this point I think we are all clear. But seriously, batteries have a much lower energy density than traditional fuels, making them impractical for long-distance ocean crossings. The middle shared the study by the Mærsk Mc-Kinney Møller Center for Zero Carbon Navigation, in which they concluded that the most promising approach in the short term is hybrid: combining electric propulsion with combustion engines. Added to this are extra risks that come from the marine environment itself: greater exposure to humidity and salinity, much more difficult evacuation conditions in the event of a fire, and the need for more demanding maintenance than in any car. Replicate the truck business model. CATL does not want to limit itself to selling batteries, as it wants to build an entire infrastructure around it, just as share in FT. It already operates in China a network of battery exchange points for trucks on highways, and now intends to take that same model to the sea. The idea is that ship operators can change their batteries in port without having to charge them, which would also eliminate that cost from the ship’s acquisition price. The company is working with municipalities and ports to develop this ecosystem from scratch; Cities like Guangzhou, one of China’s major shipbuilding centers, already offer subsidies for electric-powered vessels, according to share the middle. A personal story. There is a rather curious detail in all this. And just as account FT, Robin Zeng, founder of CATL, studied marine engineering at university before switching to electronics. “Naval engineering was his original discipline and passion,” Su Yi explained to the outlet. It has its advantages, because over time this discipline could end up becoming the next great industrial transformation of your company. Financial muscle. CATL closed 2025 with a net profit of 72.2 billion yuan (about 10.4 billion dollars), 42% more than the previous year, driven mainly by demand for energy storage. From this position of financial strength, the company has the muscle to invest long-term in a sector where margins are still uncertain. We’ll see how the company ends up doing.

Plastic is the great recycling nightmare. Car battery acid aspires to be the great nightmare of plastic

by

Have a problem with recycling. Thus, in general and even in countries that the more they try and complicate things. But, specifically, we have a problem with plastic recycling. It is a difficult and therefore expensive process, rather than producing new plastic, which leads to a scenario in which potential waste accumulates. To complicate things further, there are many types of plasticsand some are terribly difficult to recycle. But the University of Cambridge has had an idea: a solar reactor to destroy those difficult plastics. And the secret ingredient is car battery acid. The data. Before entering the ‘invention‘ from Cambridge, let’s go with some context. Recycling is not collecting, and vice versa. An example of this is Japan, a country in which there are areas in which there are 45 different categories of garbage that citizens must separate and where only 20% is recycled. In Spain, with an infinitely less obsessive systemwe are around 39%. And what is not recycled is burned in Japan and sent to landfills in Spain. Focusing on plastic and according to Cambridge researchers, the world produces 400 million tons per year and only 18% is recycled. And, as I say, there are plastics such as nylon or polyurethane that are particularly complex to recycle because their chemical structure is very resistant, which makes breaking them down complex and very expensive. plastic fulminator. This is where the discovery of the University of Cambridge comes into play. What they have developed is a solar-powered reactor that uses a very special ingredient: car battery acid. This component breaks the structural chains of the polymers into more basic chemical blocks and, therefore, easier to assimilate, such as ethylene glycol. Once the new material is obtained, a very special photocatalyst is what allows it to be converted into hydrogen and acetic acid, putting an end to that ‘rebellious’ plastic. By fluke. The team of researchers comments that the discovery was practically an accident since they knew that battery acid could be used for the process, but it was not convenient because, just as it melts plastics, it ‘eats’ the catalysts. Theirs, however, held out, and it turns out to be cheap and scalable. It is a photocatalyst composed of carbon nitride functionalized with cyanamide and integrated with molybdenum disulfide promoted with cobalt. Lots of text to say that it is a hybrid material specifically designed to remain stable in a strongly acidic environment. According to the team, it is economical and solves two problems at once: it dissolves difficult plastics and reuses battery acid that usually ends up as waste after extracting its lead content for resale. Future. In the tests, the team points out that the system has worked for more than 260 hours without losing performance and works with the aforementioned plastics, but also with that of the plastic bottles They are also not particularly easy to deal with. They claim that their discovery offers a potential cost reduction in recycling tasks because, in addition, reusable hydrogen is produced in the process. The key here is finding a way to collect the battery acid before it is neutralized for uninterrupted use to break down plastics. The team comments that they do not promise to solve the problem, but they demonstrate how waste can become a resource. new life. This approach approaches the problem from the angle of decomposition, but there are other proposals to give these plastics a second life. Because ‘melting’ them may be expensive, but if they are put into presses they can be turned directly into bricks or paving stones for the streets. This is what Nzambi Matee proposes, a Kenyan materials engineer who has proposed convert that waste into construction material. Like the University of Cambridge experiment, it addresses two problems at the same time: recycling and creating necessary non-polluting construction elements, and this idea is catching on because the authorities have given the green light to use this 2.0 brick to pave the streets of Nairobi. Returning to battery acid, the business arm of the University of Cambridge is looking to commercialize the company, but now the most complicated thing remains: making it a standard.

MG reveals the secrets of MG SolidCore Battery, the first semi-solid batteries for electric cars that will arrive in Europe

by

Without the light effects that precede a big announcement but with the security of someone who knows they have something good on their hands. MG met us in Frankfurt, met us on the outskirts of the city and put it before our eyes. The car and its tools. The weapons to continue gaining ground in a battle that seems long. Because with a quick presentation and a talk with its managers, the Chinese company revealed the two great advances with which it intends to continue gaining ground in the European automobile market: a new hybrid system and, above all, its semi-solid state batteries that will arrive with the new MG4 Urban EVa kind of evolution of the current MG4 Electric with which it will coexist in the market. In 2025, MG was the brand with Chinese capital that achieved the best results in Europe. Also in our country, where it reached 45,163 registered units. The formula for success has been based on the launch of vehicles for the access range. Cars at low prices, very spacious and equipped. But, above all, very competitive if we compare them with the competition. The strategy is paying off. Both in vehicles with combustion engines, where the brand does not have to pay tariffs, and with the MG4 Electric, which became among the best sellers in many European countries. The recipe at that time was simple: attractive price, good interior space and versions with a lot of power. Now, MG seeks to take a qualitative leap. Continue convincing and gaining ground in those who are undecided. But, above all, they bring technology that is currently not available to any other brand. Some semi-solid batteries to capture the market Our gazes, therefore, were pointed at the stage where the brand representatives were passing, but what was truly important was behind us. There, behind a curtain, the new MG4 EV Urban, a compact electric car that wants to position itself as the most advanced electric car of the moment. At least if we pay attention to its battery. At 4.44 meters long, the new MG electric car is a canonical compactor, of those that continue to triumph in the European market. To test it we will have to wait a few months but we were able to sit in it for the first time and see first-hand that we are facing a qualitative leap in quality in the interior. The car does not represent an aesthetic revolution on the outside and, of course, is less striking than the current MG4 Electric. But packaging does win. Inside, materials have improved and the perception of quality has risen. The screens are accompanied by physical buttons to control the climate and volume with wheels and controls that offer good touch. The sound of the speakers surprised me with their good quality (yes, I have to say that I don’t have the best ear among the staff). Xataka). And it has interesting details such as the controls that we already saw in the MGS6 EV on the steering wheel or a slightly rough mobile phone wireless charging surface so that the phone does not move. The new MG4 We will talk about all this in greater detail when we can get our hands on it to taste it in motion. Until then we will delve into the technology with which they want to hit the table with batteries that they already mass-produce. They are called “MG SolidCore Battery”. Because the MG4 EV Urban will be the first electric car in Europe to use semi-solid state batteries. With the promise that the car will not face a superlative extra cost. On the contrary, they told us that it will move in figures similar to the current ones. At the moment, the MG bestseller is around 38,000 euros but with the brand’s aid and discounts it is currently below 28,000 euros. What are these semi-solid batteries? It is the first step before jumping to solid batteries, the great promise of the electric car. They are energy accumulators that improve each and every one of the current aspects of LFP or NCM batteries, the most common on the market. Currently, these batteries use electrolytes that use liquid electrolytes to move lithium ions between the electrodes and thus generate electricity. With each discharge, lithium ions travel from the anode to the cathode through the liquid electrolyte. There the electricity is produced that is used by the motors. With recharging, the electrolyte takes the opposite path. Solid state batteries promise to forget about this liquid. This will allow, if the technique advances sufficiently, to have batteries with very ambitious ranges (more than 1,000 kilometers are targeted), in a reduced size and with more powerful charging and discharging capacity. And maintaining their security. The semi-solid state battery is the intermediate step. MG claims that the electrolyte liquid takes up around 20% of a conventional battery right now. With its new batteries, that liquid barely reaches 5%. Solidifying that space allows them to increase the nominal voltage of the battery and therefore also improve energy density. MG points out that these new batteries reach a density of 400 Wh/kg. Part of the secret is that the mobility of lithium ions increases their possibilities, they go from moving in a one-dimensional (LFP) or two-dimensional (NCM) to three-dimensional movement using the solid electrolyte. What does this translate into? The batteries of the new MG4 Urban EV will be smaller but will be able to travel the same number of kilometers as the current model. Although no specific figures have been confirmed, the leap forward should be qualitative because It is an evolution that feeds on itself.. If the battery is denser, it can be smaller to travel the same number of kilometers. At the same time, the weight of this accumulator is lower and the car is more efficient, resulting in better consumption data and, therefore, autonomy. But it also has other types of advantages such as less … Read more
