The 80/20 rule seemed the Holy Grail for mobile batteries. It is not as infallible as it appears

by

Scientific evidence points to a clear path if we want to take care of our phone’s battery: keep it between the 80 and 20%. It is a common practice among smartphones manufacturers, but also among some of the most popular electric cars in the market. However, this law is not infallible. In fact, developers of Grapheneosone of the safer Roms in the Android world, they have explained why Google’s operating system occasionally skips this limitation although we have specified in the settings we want. The 80/20 law. It is not something new. He is quite studied That maintaining the battery between 80 and 20% of its capacity minimizes its chemical wear, avoiding load ends. These are the ones that most degrade batteries, so working away from these areas has direct implications on the useful life of our pile. The manufacturers use it. Apple and Google have been implementing time native measures So that if users decide, the phones can limit their load. In other words, if you want your phone not to load beyond 80%, you can leave it scheduled like this to protect your useful life. In fact, this section is usually found in the battery health submenus and load optimization. But they do not always fulfill it for a reason. One of this week’s conversations have precisely to do with this rule. From Android 15 QPR2 Users began to complain that their phones were starting to carry up to 100%, deducting that the battery protection system had been deactivated. On the contrary: this 100% load is more than necessary. The developers of Grapheneosa rom that follows the rhythm of Android Stock updates, have explained why this happens. The reason. Although loads of 20 to 80% are beneficial to maximize the life of batteries, 100% charges are eventually necessary to recalibrate the estimated battery capacity. If all cycles are made without 100%, the reading on the remaining battery will not be accurate. 100% load. Similarly, loading up to 100% is beneficial to challenge the individual cells of batteries themselves. Lithium ion batteries are made up of multiple cells and, over time, some can be downloaded faster than others. When the battery reaches 100%, energy redistributes the load along the cells so that it is equal, something that only happens with the mobile loaded completely and without using for a few minutes.

BMW does not want to hear about solid state batteries

by

Have an electric car with the Autonomy of a conventional diesel It is one of the objectives of the industry. The technology of the current batteries does not allow that without including huge modules and without harming load times, but there is something on the horizon that promises to fulfill the dream: the solid state batteries that They promise to change the rules of the game. The goal is to achieve the 1,000 kilometers of autonomy and there are already companies like Saic -Dueña de Mg- They claim to have lists. It is not the only one: Mercedes says he has a that already endures those 1,000 kilometers, Byd wants to start implementing Short -term solid state batteries and Honda has just opened a megafactory of 270 million euros to manufacture them. Other greats like Ford and BMW They began to show interest For this technology a few years ago, but it is precisely the current BMW that has launched into the air that, although those of solid state are the future, the current lithium -ion batteries still have much to say. Lithium left kilometers away The interest in solid state batteries is due to multiple factors. They are smaller and light than those of Lithium ionsbut also denser, so they can store more energy. They are also loaded at a much higher speed, it is estimated that it has a useful life of between 8,000 and 10,000 cycles before starting to degrade and are safer because the flammable liquid electrolyte is replaced by a solid one. Toyota the ha qualified as “what can change the future of electric cars” and it is evident that all the main companies have interest in technology. However, in a recent interview To the Middle Autocar, the vice president of next -generation battery technology in BMW, Martin Schuster, has calmed the spirits a bit. Like so many things, money is what the singing voice carries in the passage to new solid state batteries, and Schuster has commented that BMW is eight years after needing to have an option with this battery in the market. “The most important thing is now the lithium -ion battery. It is not finished and improvements are still observed. There is no single definitive battery and will not arrive, but at this time, the lithium -ion battery can constantly improve. ” More than an improvement in performance, the real challenge is to reduce costs. For Schuster, the “main and most important” objective is to reduce costs. The manager commented that they can make solid state battery now, “but the cost makes no sense. There is still a long way to go with lithium -ion batteries. ” BMW is clear that lithium -ion batteries are present and future. A key is to improve on the existing, but above all to lower development and packaging costs Thus, plans such as Byd’s to start riding them in 2027, it seems that they do not fit what BMW has in mind because, in the end, who will pay those first batteries will be the users. “Would you be a customer willing to pay a much higher price for a solid state battery just for a load perhaps a little faster? The price is one of the most important points in the decision -making of electric vehicles, ”he added. Schuster confirmed that his GEN6 battery will be the one they use in the immediate future because they have not observed ways of manufacturing millions of solid state batteries at a low price, with high efficiency, an obvious improvement of quality and a simple integration into current cars. But, of course, Mercedes has that aforementioned battery with 1,000 kilometers of autonomy and from Autocar they asked him about the matter. “They are in a price range that is not competitive,” he replied. “That is the reality today and, when we see that they compete against lithium -ion batteries -in that cost/price relationship -then we will take note,” said the manager. For Schuster’s words, it seems that BMW has a decade ahead To think about the introduction of solid state batteries in their vehicles and Neue Klasse With that battery Gen6 They are the bet of the German house. And these batteries will also be integrated into other models, such as the SUVs, being the X5 of 2026 the first in receiving them. We will see if they maintain that bet at the time when the rest of the brands are launched by those of solid state, since it is not only the traditional marks that are in the fight: The Chinese They are very interested and giant like Huawei either Samsung They are developing their own.

China has in his hands the world production of chips and batteries thanks to the gallium

by

On December 2, one of the most aggressive Chinese sanctions packages of those who have deployed USA so far entered into force. And is that the government led by Joe Biden included 140 more companies on your blacklist. These prohibitions are aimed as Chinese companies that design and produce The lithography equipment involved in the manufacture of advanced semiconductors, hence the impact they are presumably having on the Chinese chips industry is deep. As expected, China soon react. Just one day later the government led by Xi Jinping announced the prohibition of export of critical minerals to the US. Among them are three essential chemical elements for the semiconductor industry, as well as some materials that are characterized by their extreme hardness, and that, therefore, can be used for military applications, such as gallium, Germanio and antimony. According to Japan, restrictions will affect the supply chains of chips and batteries China currently produces 59.2% of Germanio, 48% of the antimony and nothing less than 98.8% of the gallium. “This measure entails a considerable escalation of the tension to which supply chains are already subjected. It is difficult to access some raw materials,” Jack Bedder holdsco -founder of the Project Blue consultant. “It is logical that China responds to the growing restrictions of current and imminent US authorities with their own restrictions on these strategic minerals,” Peter Arkell points outPresident of the Global Chinese Mining Association. “It is a commercial war without winners.” Japanese Gallium imports since China have fallen no less than 85% between August 2023 and the same month of 2024 Several Japanese officials and executives linked to the semiconductor industry are aligned with Jack Bedder’s thesis. According to Financial Timesthese experts are warning of the US governments, Japan and their allies that the restrictions imposed by China on Galio’s export and other strategic raw materials will affect deeply to the supply chains of semiconductors and batteries. However, this is not all. Japanese officials suspect that the Chinese government could force them to inform them about all the products that contain Gallic exported by Japan to the US. Otherwise the administration of Xi Jinping could even more harden the measures that have caused that Japanese Gauling imports from China have fallen no less than 85% between August 2023 and the same month of 2024. Japanese companies are the ones that most Gallic, Germanio and Grafito consume. More than US, European, Taiwanese or South Korean companies. If the Beijing Government hardens its control over the Gallium the electric motors of Tesla cars from Japan, the lasers of Gallium Arseniuro used by Broadcom or some of the chips integrated in Apple’s iPhone could be affected by China’s export licenses. This situation reminds us of something important: no industrialized country can remain outside the economic and commercial war that the US and China hold.

Byd has already placed solid state batteries in their electric cars: we have good and bad news

by

If there is a technology that has been playing for years in the world of electric cars, that is that of solid state batteries. Companies like Mg They have already advanced that they are the future for the electric car to consolidate 1,000 kilometers of autonomy, Honda has opened a megaphabrica dedicated to them, and Byd just announced nearby plans to start implementing them. The Chinese company has placed when it intends to start marketing electric cars fed by this type of batteries. Spoiler: There is not too much To start enjoying them. In the second annual battery summit and solid state development of China during the last weekend, Sun Huajun, the CTO of the Byd battery business, gave relevant information about the company’s progress. {“Videid”: “X8T0ABA”, “Autoplay”: False, “Title”: “Yangwang U9 and its body control”, “Tag”: “Yangwang U9”, “Duration”: “23”} According to your statements, Byd is ready to Start marketing vehicles with solid state batteries from 2027. Between 2027 and 2029 its first phase will begin, starting from a limited production as a demonstration phase. From 2030, this production is expected to start working on a large scale, beginning to democratize mainly in its highest range vehicles. According to byd, this type of batteries are more stable, allow faster loads, and greater autonomy. In Xataka Byd hits Tesla in her great promise of the future: "Eye of God" It is your free autonomous driving system in your cars Although 2030 will be presumably the year in which this type of batteries will have more presence, the adoption will not be massive. The cost of solid state batteries remains higher than that of LFP batteries, so this second type of batteries is expected to remain alive for at least 15 years. Those of solid state will be Focused first -line products Already luxury brands of the group, as a denza or yangwang. Despite this, the objective of giants such as Catl is to achieve mass production that ends up making this type of batteries more accessible. These are the Holy Grail For the future of the electric car, and incorporating them into mass models is the next step. Image | Byd In Xataka | Byd’s growth is unstoppable. Now he is at the gates of overcoming annual sales to Ford and Honda (Function () {Window._js_modules = Window._js_modules || {}; var headelement = document.getelegsbytagname (‘head’) (0); if (_js_modules.instagram) {var instagramscript = Document.Createlement (‘script’); }}) (); – The news Byd has already placed solid state batteries in their electric cars: we have good and bad news It was originally posted in Xataka by Ricardo Aguilar .

Novo Energy wanted to stand up to Chinese batteries for electric cars. It has ended in the hands of a Chinese company

by

Point and apart for the soap opera of the Great European hope In the battery segment for electric cars. In the European assault on electric car industryVolvo and the Northvolt battery manufacturer founded Novo Energy. Both were Swedish and it was a Join Venture with the aim of producing batteries in Europe. It seemed that everything was going to be A ROSA pathbut a few years later and after thousands of layoffsNorthvolt sell His participation in Novo Energy A Volvo. And behind Volvo is Geelyan important Chinese holding. Culebrón. Things stopped going well for Northvolt practically from the beginning. During the first years, the European Investment Bank, BMW, Goldman Sachs or Volkswagen invested sums of hundreds of millions of euros in the company. The Swedish company, founded by two Exegutive of Tesla, became the great European promise to create batteries and be the heart of that European flying towards the electric car. In a market increasingly controlled by ChinaIt seemed like a great idea and everything pointed in good sense. In addition, together with Volvo they founded Novo Energy in 2021 to produce the batteries of both Volvo and Polestar. However, things began to twist in 2023, when it was uncovered that the company had been operating with losses of 1,000 million dollars during the first nine months of the year. And, in 2024, the situation exploded. Last nail in the coffin. Everything happened very fast. After the delays in the delivery dates, BMW canceled its agreement of 2,000 million euros, there were a series of employee deaths in work shifts, fired more than 1,600 workers in September and, shortly after, the bankruptcy arrived. In November 2024, Northvolt requested bankruptcy protectionarguing that they had 30 million in cash and, with them, they could only operate for a week. The hole they had was 5.8 billion dollars. A skinny dog, everything is fleas, and a day later one of the founders resigned, arguing that the company would need 1.2 billion dollars to save itself. After a few days of 2025 in which the company was still looking for financing, something that nobody seemed willing to do, sales arrived. It was even rumored that Catl, the main Chinese rival in battery manufacturing, I could give a hand. Volvo. After getting rid of some services, this January 29 we learned that the Swedish company sold its participation in Novo Energy to its partner in this adventure, Volvo. It is something that does not catch by surprise, since, as with BMW, Volvo saw that Northvolt’s delivery plans were not being fulfilled and in October last year he showed his interest in acquiring participation in Novo. Last week, Novo Energy advertisement which had to reduce its workforce by 30% due to “the changing market conditions and a modified business plan”. Northvolt wants to reduce everything possible and focus on its Swedish plant, but they have also signed an agreement with Volvo to explore joint collaboration paths in the future, so everything is not lost. China looks out to Europe. Therefore, Volvo will now be the one Novo Energy, we will see if alone or with partners, but the interesting thing about this operation is that, although Volvo is a Swedish company that is in the bag of his country, the matrix is ​​Geely, A Chinese holding. They are present in multitude of companies and sectors, with an important participation in Mercedes-Benz, Aston Martin or Lotus, as well as co-owners of smart, polestar and with a participation of more than 80% in Volvo. It is curious that Northvolt was born to stand up to the Chinese battery industry and that the Join Adventure That I had with Volvo to produce batteries in Europe, now, is controlled by a Chinese company, in the absence of seeing the resolution of the authorities. And all this, shortly after Tariffs imposed by Europe To the Chinese electric car.
