China has commissioned the largest battery of all its electricity network to an unexpected company: Tesla

by

China has no problem parking Commercial tensions with the United States If it is for the benefit of the country. And the country needs Tesla for an increasingly pressing task: stabilize a network with more and more renewable participation. The largest battery in the largest network. China has selected Tesla to develop what will be the largest energy storage station at network scale throughout the country, surpassing the 1 GWh battery park in Shandong. The American giant He signed an agreement with the local government of Shanghai for 4,000 million yuan, 557 million dollars, to lift a gigantic station that can actively participate in the spot electricity market. China has the largest electricity grid and a renewable energy generation capacity in constant and massive growth. The Tesla battery station You can buy and store energy When demand and price are low, and then sell it to the network during consumption peaks, helping to balance supply and demand, and improving the general stability of the system. The business is in the megapacks. The Energy Division of Tesla does not stop growing, to the point of become a fundamental pillar of the company. The project engine is megapacks, Large storage units in 3.9 MWh batteries which can be used to stabilize the electricity grid and avoid supply cuts. It is no accident that the most ambitious battery station in China will be built in Shanghai. Just four months ago, Tesla launched a new Megapacks factory in the Lin-Gang area, where is also its car factory “Gigafactory Shanghai”. The new “Megafactory” is the first plant of this type out of the United States, and although it has barely been operational since February, it has already produced more than 100 megapacks. Tesla gets into the patio of Catl and Byd. They are “only business”, but the movement is still striking considering that Tesla is competing with Catl and Bydthe two Chinese giants who take 54% of the world battery market. Another way to see it is that China needs many batteries By the end of the year, the government expects to reach 40 GW of storage. But taking into account that the country installs half of the entire new capacity for renewables (329 GW in 2024), by the time the Tesla battery station in Shanghai enters service, the goal will have continued to rise. And Tesla will be just one of the puzzle pieces. Image | Tesla In Xataka | China manufactures more batteries than anyone. The problem: they accumulate next to the solar panels without storing energy

20 years ago the button of a Samsung unleashed madness. So much that Mediamarkt had to take away the battery

by

A phone with such a curious button that Mediamarkt had to take away the battery so that users did not abuse it. It is the story of a Samsung proposal born 20 years ago, with a mechanism that aroused the curiosity of anyone who approached this phone. As you collect Xataka mobileit is one more proof of how Samsung has been the king of folding format for more than two decades. Launched in 2004, the Samsung P510 It was a phone Concha typewith double screen (interior and exterior) and a fairly particular characteristic. At that time, Concha type phones were not so different from the folding now: some force had to be made to open them. But Samsung wanted to go further with this particular model, and completely mechanized the operation of the hinge. It was enough to press a button so that the phone opened and closed its upper part, the lid. Being an electronic mechanism, this curious opening-giving was accompanied by an addictive sound. Nils Raetting account, Technological journalistthat there for 2004 he was working on an old German Saturn. Among the most prominent devices in sales in its store, the P510 takes the prize. Raetting reports that the influx of curious who went to the store in order to test the button was high. To this point, that the battery had to be removed from the exposure model so that both potential clients (as simply curious) did not abuse this mechanism. Social networks show Some short videos with the phone mechanismstill functional in several well preserved units. Surprise the speed at which the phone opens and closes, taking into account that we talk about a phone released in 2004. Although the P510 does not enjoy a memory as prominent in memory as other legends in the style of Motorola Razr V3 or the Nokia 6820, Some units are still sold on websites like eBay about 100 euros. We see descriptions such as “completely motorized, weird”, since this is a trend that the rest of the manufacturers did not follow. In fact, Samsung herself continues to bet in the middle of 2025 for the folding format of the shell type on phones such as the Galaxy Z Flip6. A telephone that there is no trace of a similar button, and to which it would not be easy to implement it given the folding nature of its panel.

23 years ago China gave the US a lesson. Thanks to it today dominates the battery industry overwhelmingly

by

The German-American physicist John Bannister Goodenough patented the technology that allowed to manufacture Iron and lithium phosphate batteries (known as LFP for its English denomination) in 1997. In 2019, when he was no less than 97 years, he was awarded the Nobel Prize for his contribution for his contribution to the development of lithium ion batteries. However, Goodenough made a mistake. An important mistake: he failed to transfer his innovation to the American industry, so its impact on the West was minimal. Wang Chuanfu, the founder of the Chinese company Byd, did not make that mistake. In 2002 he perceived the potential of the technology that Goodenaugh had invented, so he asked his research and development team (R&D) to investigate the technology and capabilities of LFP batteries with the purpose of minimizing the dependence that China of the nickel and cobalt had. That decision I guide Byd towards the leadership position Shared with Catl currently occupied in the battery production industry. In fact, in 2008 he placed in the market The first car in the world Equipped with an LFP battery. China manufactures 57% of the batteries used by electric cars China is currently The largest electric vehicle market of the world. In 2025 in this country more electric cars will be sold for the first time than with combustion engine thanks to some extent to government subsidies. In addition, China is the largest electric car exporter on the planet. In 2023 he exported approximately 1.7 million electric vehicleswhich represents more than 30% of its total car exports. However, its international expansion is being seriously conditioned by the tariffs that are imposing USA or the European Union, among other regions with very serious difficulties to compete with the Chinese electric car. Finally, as we have seen, China is also a world leader in The production of lithium batteries. If we stick to electric cars the country led by Xi Jinping Fabrica 57% of batteries that these vehicles use. CATL and ByD are the largest lithium batteries on the planet with a market share in 2024 of 37.9% and 17.2% respectively, according to the consultant Sne Research. In 2017 for the first time the market share of NCM batteries surpassed that of LFP in electric cars China has reached this leadership position due to several factors. On the one hand it is The largest producer in the world of lithium and rare earths, which are the main raw materials used in the manufacture of batteries. In addition, it controls the processing of these materials and is capable of producing large -scale batteries and with a very competitive price. However, in this recipe there is one more ingredient that we cannot overlook: byd and Catl lead the global battery industry thanks to their capacity for innovation and adaptation. In 2017, Chinese government subsidies prioritized the development of Nickel batteries with greater energy density, so much of Chinese battery manufacturers opted for NCM technology. These lithium -ion batteries use a nickel (ni), cobalt (co) and manganese (mn) cathode, hence their name. And byd lagged. In fact, in 2017 for the first time the market share of NCM batteries surpassed that of LFP in electric cars. And in 2019 the NCM batteries already dominated the market. But Byd did not give up. Wang Chuanfu was convinced that the really important security was, and, therefore, the thermal stability of the batteries, so it launched a new R&D project that concluded with The tuning of Blade batteries. These devices are thinner, have modular structure and can be easily integrated into the chassis of electric cars. This bet went well to Byd. At the end of 2020 this company and catl They controlled 66% of the Chinese market of the LFP batteries for electric cars against 6% that added in 2019. This is the authentic strength of the two Chinese companies that lead the world battery industry.

The Catl battery factory in Aragon promised to generate thousands of work. At the moment, 2,000 Chinese will be left

by

1,847 Chinese workers. That is the estimated figure that, according to The Aragon newspaperwill arrive in Figueruelas to lift the battery production plant for electric cars that Catl and Stellantis signed months ago. Then it was sold that some 3,000 jobs would be created but, for the moment, almost 2,000 employees will come from the Asian country. The data. The first time that the subject was discussed Chain ser Last May. Then it was pointed out that Catl would arrive in Figueruelas (Aragon) with more than 2,200 workers from China who will raise the new battery factory for Stellantis “, in the words of Mayor Luis Bertol. The figure, as we see, has clarified until it closes in the aforementioned 1,847 workers. The town faces a challenge, since those almost 2,000 workers would fold the current census of inhabitants that In 2024 it was estimated at 1,240 neighbors. Obviously, the vast majority of factory workers that Stellantis has in the municipality live in nearby towns and, above all, in near Zaragoza since they are currently accounted for about 5,000 regular employees in the property of the car manufacturer. A promise. The new factory that Catl and Stellantis will raise in Figueruelas will be The largest battery producer of electric cars from our country, even ahead of Volkswagen’s in Sagunto. Then it was announced that it arrived with an investment of 4.1 billion euros under the arm. But it was also promised that it would create 3,000 direct jobs. The figure leaves the declaration of general interest (say) approved by the Government of Aragon to open the doors to the express processing of the aid, as collected in December 2024 in The Spanish. “The noise is in the media”. Since the news was known, the coming and going of the numbers on Chinese workers has raised some dust. It is not clear why CATL needs to bring almost 2,000 Chinese workers to raise their factory. Nor if that work could have been left in the close environment or if knowledge is missing for it. Similarly, it has also been put on the table how Figueruelas will face its population. Bertol pointed to The Aragon newspaper that “noise is more in the media than among our neighbors.” Explain that the idea is to start prefabricated housing near the factory facilities. And he shields that there was already a similar situation in the 80s when General Motors lifted the Opel plant (which now belongs to Stellantis) in the town. Is it legal? According to The Aragon newspaperChinese workers who will arrive in Figueruelas will not be only operators that aim to lift the factory. Intermediate controls are expected and, of course, high -ranking controls. To do this, Catl will apply the framework of the Unity Law of large companies and strategic groups (Law 14/2013) Born to promote the arrival of these macroprojects after the 2008 crisis. This law is included, for example, the streamlining of residence permits for highly qualified workers. Is Chinese labor needed? “At the start you need people who, getting out of the plane, know what to do in that factory later.” Thus defends Bertol, mayor of Figueruelas, the arrival of these workers in the city. “You don’t have to get your hands to the head for this matter, it is a logical and normal process,” he explains to The Aragon newspaper. “Catl brings battery technology, which is also the best in the world market, and brings its machines and ways of working.” Without these workers it would not be the factory in motion although, yes, it is not said how long they are expected to maintain their work in the Aragonese town or if formations will be established to local workers. Other cases. Although striking, the case of Figueruelas is not exceptional either. Catl’s landing in Germany was similarwith investments that came from the hand of Chinese workers who could train local workers but, above all, they did Full performance What was lifting. Byd has worked similarly on his arrival in Hungary. And it is something that works in the two West-Oriente directions. Following the tariff war that the United States opened with all the countries of the world, the debate of Why Apple did not make its iPhone in the United States. Beyond costs, there was a simple reason: there is a lack of people formed. Photo | Stellantis and Catl In Xataka | Nissan pointed to the electric car as a future plan. It will fire 9,000 employees and prove Toyota

China is attending a crazy race to demonstrate who has the safest battery. That’s why they crush them with tanks

by

If I point to the volume, I am not sure if I learned a lot or little in the university. But I am clear about one thing: I learned what was news or, at least, the criteria to point out whether an event is news. When the issues that can be discussed are put on a wording, different aspects are valued. Truthfulness, current, proximity … and novelty. And if an event comes out in the media it is because it is usually “unique, unpublished, unlikely or out of the ordinary.” I don’t say it, University institutions say. That is why it makes little sense to affirm that electric cars are dangerous based exclusively on news. We could do it if we had relevant studies that pointed out that the number of electric cars is notoriously higher than those of combustion. But it is not the case. We do know that the fire of an electric car is more complicated to turn off and more virulent. That is why it is logical that take action on ships where they are transported or working on New protocols in fire bodies. That does not mean that the risks of this technology are greater. In spite of everything, it also enters within a certain logic that when a fire is given or any other risk situation, the alarm voices are multiplied. From municipalities where They consider whether to continue buying electric cars a parking lots that prohibit their step. In that case, companies only have to show that their batteries are as safe as any other component of a car. As if I could pass them a tank over them. The crazy idea of ​​a tank Although it seems nonsense, it makes sense that manufacturers refine ideas when demonstrating the safety of electric car batteries. Keep in mind that, for example, In South Korea, an intense debate has been lived on whether or not these cars may accumulate in garages after A Mercedes Eqe will explode last year. When Byd arrived in Spain he had a challenge ahead. I needed to make themselves known and, above all, demonstrate that it was a company in which you could trust. We already know the prejudices towards the Chinese product. As a journalist, I don’t know how many times I could visualize This video in which a nail is going through an LFP battery without anything happening. It was one of the classic images. The other was the pressure tests. When too much pressure is applied to a battery (electric car or any other device) runs the risk of experimenting A thermal leak. Heat grows inside, chemistry is released and the pressure increases to cause an explosion with the consequent fire. To avoid this, the housings are designed to release the accumulated pressure inside, with the aim that if we have an accident, the pressure exerted on the battery does not cause an explosion. And the company can already tell us about figures and data and everything we want. But nothing better than the visual. Click on the image to go to the original tweet That is why Geely, explain in Carnewschina He has taken his new “Aegis Gold Brick Battery” a 36 -ton tank and has passed it over. And what happened? Nothing. Nothing at all. The battery did not give any sign of damage despite receiving 1.8 times the minimum pressure required by Chinese institutions to standardize a new battery. You can see the video on this link. They point out that the tank not only He crushed the battery On one occasion. He passed over it, returned on his steps and continued to crush her repeatedly. And did the same going over individual cells. The battery package “maintained its structural integrity without bulges, leaks, fires or explosions,” they emphasize. To overcome the test, the aegis Gold Brick Battery has been designed with a double wet coating that facilitates the dispersion of heat and thermal leaks since it is especially heat resistant to heat generated by aluminum oxide. It also has liquid-electrical separation of the materials. Photo | Geely In Xataka | Samsung has just revolutionized batteries for electric cars. In autonomy, in load time and in useful life

The battery quality in mobiles

by

I have interviewed enough brand leaders to have something very clear: the battery is one of the characteristics that most influences the purchase of a smartphone. In Europe we seemed doomed to a very specific figure: about 5,000mAh that remained immutable generation after generation. Chinese mobiles have begun to mark a trend with 6,000mahbreaking it in specific cases such as the Redmagic 10 Pro with its 7,000mah or the recent one Honor Power, with 8,000mah. In addition to the clear war in relation to the milliamps-Hora this eagerness for Chinese manufacturers to bring the best batteries goes further: the focus is in their quality and usability. Crazy about capacity. Broken the 6,000th barrier, we published a piece that has not taken long to materialize: one regarding that this roof surpassed, We don’t know where the limit is. Honor has already managed to introduce 8,000mah On a phone with an 8mm thickness, the same of any other traditional smartphone. Realme rises to 10,000mahabsolute madness. From one year to another, the 5,000mAh of the competition have become an obsolete figure, although everything that shines is not gold. A change in industry. That this capacity has been unlocked has a main responsible: the Silicon-Carbon batteries. Here manufacturers have been pioneers by introducing this technology, which allows you to introduce much more energy capacity in the same size. From a time to this part, this type of batteries has become more and more popular, although some manufacturers (including the Chinese) They reserve them for China for a simple reason: costs. Beyond silicon. Longevity is another obsessions for this 2025, and OnePlus is the best example. His OnePlus 13t It is able to function without using battery, but electric current, when plugged in the current. This function, which we already saw in the past in Redmagic mobiles (and Sony already flirted with it in some Xperia), is ideal to preserve the life of the battery on the scenario that suffers the most: when it is connected to the current making discharge cycles. A perfect ally. A good part of the responsibility in these advances has it Catlone of the giants in the battery industry (mainly in the industrial and electric car spheres). In recent years, Catl has collaborated with manufacturers such as Realme for the joint development of batteries, betting on silicon-carbon as material. A dart to the rest of the manufacturers. The 6,000 (or more) MAH are becoming a standard, and now the glove will have to pick it up the rest of manufacturers outside China. Betting on this type of batteries is not cheap, but launching a terminal with a 5,000mAh battery will begin to become a competitive disadvantage for the rest.

And suddenly, a great battery and the Sun of Murcia saved me from the great blackout

by

After a crisis, a couple of disturbing war conflicts, Trump’s second mandate And a worldwide pandemic, The biggest blackout in Spain I shouldn’t have caused me so much concern. But at home, at three o’clock at the beginning and with the children newcomers of the school, his nervousness was very evident. And ours. No electricity grid for almost 12 hours And disconnected from the world almost the same hours except for the blessed radio to batteries, at home the tranquility for the tense and indefinite wait came to us in the most unexpected way: the radiant sun of Murcia and some test batteries in Xataka. This is the story of how some Solar panels connected to a large battery The great blackout of Spain mitigated at home. The reality that everything works with electricity The entrance/exit door of the work center, which we usually opened through an application installed on the mobile, only paid attention to our need to exit urgently when the concierge, analog key in hand, opened it and threw from it under the almost 30 degrees of two in the afternoon in Murcia. At the end of April. “Googlear” if the suppliers of the service stations need food to work, something that would have taken me 10 seconds at another time, was the beginning of many hours of energy uncertainty whose solution did not remember that I had at home On the way by car home, with the deposit near the reserve and without knowing for sure if the suppliers need food to function – or possibility of Googlear the answer to my doubt – the radio was the only point of connection with the real situation. Because the theories about what was happening did not take 10 seconds to run from Boca by ear and another ear … Suddenly, everyone had spoken with a family member abroad who confirmed without any doubt that it was a European issue. What European, world. An “makeshift” installation of solar panels on the home terrace With the few news that I could hear about what was happening I got home. The atmosphere was very similar to that of pandemic, with uncertainty dominating everything. And the feeling of living too many things for the first time. The noon food had to improvise according to very clear criteria: use the perishable of a refrigerator that we did not know when it would be operational and resort to gas barbecue. Yes, the induction cuisine does not get along with the lack of electricity. Already with the serenity that gives the stomach well attended, as a game to calm the kids, we analyze the situation at home and draw a plan for the afternoon. We are looking for lanterns, laptops, “powerbanks” and any device that could be charged. The smartphones and tablets between them. To do so we had an immense, literally, allied at home: some ecoflow batteries tested in Xataka. Time to recharge everything rechargeable. And cook the “cooking” With the internal load of the batteries, a main of 4,000 mAh and an assistant of the same capacity, almost 80%, the four plugs and four USB ports (two of type C and two of type a) they began to recharge everything that we found at home. Including the batteries that we already know that they must be in every emergency kit that boasts. Without the possibility of loading of any kind, the solar batteries of the house offered a recharge point to family and friends who requested it The objective was that, if the situation was extended until night, we could have operational devices And of course Lights ready so that, at least at home, the situation was the most similar normality. Batteries, camping and reading/leisure lights for the long wait Since it was still the beginning of the afternoon in Murcia, the batteries continued to recharge to the usual rhythm in their “rush hour”, about 1,000-1.200 W per hour. One of the great advantages of these Ecoflow batteries for recharge is that they can be feed both from the electricity and connected directly to solar panels. The radio we were about to “recycle” last summer We take advantage of this situation of energy surplus for both less important issues and relax with a fresh coffee and to use certain thermomix type appliances, the microwave or a small electric oven. Everything we could take advantage of that solar energy seemed to us a good idea at that time. Things of situations that are first lived. Mobile of friends and family who lived near them were recharged with our house battery We also rejoice at home of having stored an old analog radio because, without data or functional telephone, it was our only source of reliable information. The great blackout was not this time through streets. No neighborhoods. Not even in cities. But the most alarming was that the duration of it was a great unknown. So the very few moments of connectivity allowed us Offer our batteries to family and friends They lived close to recharge their mobile phones. And without sun, the batteries take control of the house With the different official information about everything that happened arriving via radio but on droppers, the sunset reached us at home with the unknown about what would take the electricity grid of our Murcia area to be operational. So without a sun, it was time to start squeezing the Energy stored throughout the day until it exhausts her. At night, the solar battery was ready to use the stored energy and feed the refrigerator for hours and thereby save food for a very valuable time The system that we have ecoflow proof does not allow energy injection to the home network itself if it is not connected to the general. But his poOutput tenance of up to 4000 W gives us the possibility to use powerful appliances in a timely manner, as we did with the water tank or microwave. At night, in … Read more

How to load your mobile battery when there is no electricity

by

Let’s tell you How to load your mobile battery when you don’t have electricityeither by some blackout in your area or for some other situation. Because in these cases it is normal for us to throw a lot of mobile, and that it is the device that we need most to have loaded. The mobile has become the environment with which we communicate, we inform ourselves and entertain ourselves, so it is important to keep it with drums. That is why we are going to give you some tips that will help you keep it loaded. Load your mobile without electricity Let’s give you a series of Methods to load the mobile without electricity at home In list format, with descriptions of why each of the methods we recommend. Of course, there should be Prepared for any light of light In some cases. These are the methods you can use: Use an external battery: If you have an external battery at home, you have a treasure in these cases. It is the main method you can use. If the battery has a good capacity of about 10,000 mAh, you should have several loads of your mobile. Plant it with your laptop’s battery: If you have a laptop at home that still has a battery and you will not use it, you can connect your mobile and use the laptop as an external battery. Of course, this will exhaust the computer battery very quickly, that is, be careful if you are going to need it. The battery of your car: You can also go to your car and connect it to one of the loaders you have. In these cases, it is important that you keep the car started, and to be able to circulate with it, so that the battery is not exhausted and you can start it later. Solar or crank batteries: There are other types of batteries or loaders that you can use, such as those that use the sun to load (although in a very slow way), or those that have a dynamo or crank to generate electricity. They are little efficient methods, but they are. Try not to use the mobile much: Finally, we are going to advise you that in these cases try not to use the mobile too much, especially not use demanding games or apps that drain the battery. Use the energy savings mode you have and reduce the brightness of the screen, also turning off Bluetooth, GPS or Wifi to maximize the battery life you have.

We lead all my life by measuring battery capacity in mobiles. Mah’s war makes no sense

by

How many more mah, better. We have been thinking about the specifications of a phone and, to a large extent, is something true. A greater capacity battery is usually a more capable battery with respect to a smaller. Despite this, there is a somewhat more complex unit of measure, but even more precise, traditionally used in the technical sheet of computers: Los watts-Hora (WHE). This is the most precise way to determine how long we can use our device, without leaving the capacity to your fate. We are going to explain, without delving too much into technicalities so as not to complicate your life, why we have been imprecisely measuring the battery capacity of our mobiles. Why do we measure in mah. The commercial standard for the phones battery is the Miliamperio Hora, a very useful measure for small devices with constant voltages. In addition, it is much more striking to indicate closed figures, such as 5,000mAh, than to tell that your mobile has a 19.4 Wh. However, its two main problems are, in the first place, when there is a voltage variation (you will soon understand why) this measure ceases to make sense. Although MAH is easy to understand, it does not provide an exact estimate of available energy, which can lead to incorrectly assume how long the battery will last in specific situations of use. Water measurement time. The watts -hora (WH) are the most precise unit to measure battery capacity, since they reflect the amount of energy available depending on voltage and current. He watt (w) It is the power unit, which indicates how much energy is consumed per unit of time. It is more useful to know how the battery will be used during the daily use of your mobile. The battery voltage is not constant: it is varying as its percentage of load and useful life changes. A battery, At the end of your useful lifeIt does not provide the same voltage as when it is new. In fact, if you have a modern car or motorcycle, you surely have access to real time voltage and you will see how you change as you use the vehicle. The mobile battery is lowercase compared to these, but also suffers small voltage variations. The ease of calculation. Even if the voltage was constant, the watts time would be an ideal measure. For example, if your mobile phone had a 5,000mAh battery and a typical voltage (the most common in phones) of about 3.85V, that battery would translate into 19.25 WH (capacity (MAH X Voltage / 1,000). Knowing the data, it would be enough to know the consumption in watts to deduce almost exactly how much the battery would last. In a concrete situation, as a very demanding game that leads to consume 6W constantly the division would be easy: 19.25 wh/6W = 3.2h. A data that stables: about three hours of screen with the mobile spending all rag This is why in segments such as computers, where consumption is crucial and marketing (something) less important, WHH is established as a standard to measure battery capacity.
