China has no rival in batteries and solar panels. It is already ready to also destroy Western pharmacists

by

China’s quota in the world photovoltaic cell market Broken 80%and for the moment only India seems to have the ability to disturb him in the long term. Its manufacturing capacity is 17 times greater than the rest of the planet togetherwhich has encouraged the Chinese administration to support the manufacture of More than 1,000 GW in N -type cell capacity As the other countries fulfill their net emission commitments. On the other hand, 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 manufacturers on the planet with A market share in 2023 34% and 16% respectively. Its absolute leadership in these two sectors is the result of a strategy that prioritizes investment in R&D and large -scale production to shoot competitiveness. Now Chinese biotechnological companies plan to apply this successful formula to medicines. China has the ability to drastically reduce the cost of medical care “We can reduce the costs of medical care and benefit more people through technological innovation and the improvement of efficiency (…) the recent achievements of China in the field of biotechnology show that it is possible to do it,” says Da Liuthe CR-CP Managing Director Life Science Fund, a risk capital investment group created by the Chinese state and the Thai chain Pokphand Group conglomerate with the purpose of investing in biotechnology companies. “We can reduce medical care costs and benefit more people through technological innovation and efficiency improvement” Chinese pharmaceuticals and biotechnology are living a “Deepseek”. This means simply that the medications they develop are every time most demanded by multinational corporations. What the latter pursue is to obtain the necessary licenses to market, produce or distribute the medications developed in China without elaborating them from scratch. Just three weeks ago the American investment bank Jefferies published a report in which he argues that Chinese companies and assets are extraordinarily competitive thanks to “their efficiency in costs, their small deadlines and the quality of the resulting product.” Interestingly, in seven of the ten main agreements carried out by the global pharmaceutical industry during the first semester of 2025, Chinese licenses were involved, According to the Pharmcube consultant. The success of the Chinese pharmaceutical industry is supported by a strategy very similar to that which has led this Asian country to lead the markets of solar panels and lithium batteries. However, China does not have it as easy as it seems. And it is that the geopolitical tensions that mainly support the countries led by Donald Trump and Xi Jinping are very difficult for Chinese biotechnological companies their international expansion through mergers with foreign companies. According to Liu What they need to transform into great multinational actors in the pharmaceutical industry is to achieve a dominant position in at least one or two fields of biotechnology.

In the search to eliminate the lithium of the batteries, we have found the best candidate: multivent ion batteries

by

Lithium ion batteries move the world and, in the era of electrification, every time They are more important. They have a series of limitations and Lithium is a finite resource With a high environmental impact, which is a problem if we want to electrify mobility. There the future solid state batteriesbut meanwhile, a group of NJIT researchers He has had an idea to give more life to the current technology: squeeze the maximum current batteries. As? With multivent ion batteries. Multivalent ions. A team of researchers from the New Jersey Institute -Njit- had an idea. If lithium is key to current batteries, but also scarce, We could use more abundant elements such as magnesium, calcium, aluminum or zinc as a replacement or to ‘dopar’ current batteries. The objective was to maintain, at least, the properties of current batteries and, if possible, improve storage benefits without depending on lithium. There the multive ion batteries come into play. If Ion-Litio have only one load, multiveous ion batteries that use the aforementioned elements allow two or even three positive charges. This property, in theory, allows you to store more energy by ion. Not everything is perfect. This property, as exposed in the studyit allows to store more energy by ion, but if they are not used it is because they present an important technical challenge. Multivalent ions are larger than lithium and have a greater load, which makes their movement difficult within current materials. To make it easy, imagine that the interior of the cells of a lithium -ion battery is a sponge with a certain number of recesses that catch particles. In a multivete ion battery, it has more holes and each one catches more particles, but the sponge is also greater. Accelerated by AI. That was the great limitation of the technological industry, but what NJIT researchers have done is to put the artificial intelligence To work. In this context, the use of AI is ideal because it allows simulating a large range of possibilities, of which the most convincing to test them. The end of the AI was to find new viable compounds to create multive ion batteries and, for this, they used a dual approach. On the one hand, a model called CDVAE (Variational Crystal Dissemination Self -coach) that was trained with known crystalline structures to generate new materials. On the other, a model of LLM LLM LANGUAGE Aphinated to select only the most thermodynamically stable structures. When they finished the work, they discovered five new porous metal oxides that are shown as ideal for transporting multivalent ions quickly and safely. “One of the greatest obstacles was not the lack of promising chemicals for batteries, but the practical impossibility of trying millions of material combinations,” said Dibakar Datta, leader of the research team. “We resort to generative artificial intelligence as a rapid and systematic way to explore that vast panorama and detect the few structures that multivalent batteries could really do practices.” Structures isolated by AI models. Section A is that of the CDVAE. The B is that of LLM Beyond the batteries. The team states that it validated the structures generated by AI using mechanical-chanting simulations and stability tests, confirming that these isolated materials could be synthesized with great potential for applications in the real world. Currently, and with those results, from the NJIT they are collaborating with other laboratories to synthesize and test those materials designed by AI. And something that Datta highlights is that, as a collateral effect on research, they have demonstrated once again that AI can be “a quick and scalable method to explore any advanced material, from electronics to clean energy solutions, without relying on extensive tests by test and error.” Once the best results are isolated, of course, it is time to try them in the real world, but much of the previous work It accelerates considerably. A mere patch? Now, although changing the ‘formula’ of lithium -ion batteries can be a good patch, the objective of the industry is still put in the implementation of solid state batteries. The catalyst in them is not a liquid, but a solid that allows us to solve many of the problems of current batteries, while offering a Greater energy density and faster load times. They are batteries that are already developed and that are being driven by Much of the automotive industrybut the problem is that it is a more expensive technology and is not settled. Bringing it to the real world, for example, Mercedes is already in itwhile other brands like BMW say that, for the moment, they are not in their plans due to precisely the price.

Chinese mobiles have batteries 11% higher than those in the rest of the world. The culprit is called sic

by

Chinese smartphones have a clear advantage: their batteries are 11% larger than those in the rest of the world. A consolidated suspicion that is now measured thanks to Counterpoint Research. The average in China reached 5,418 mAh in May 2025, compared to 4,900 mAh in the rest of the world. The difference has expanded to exceed 500 mAh in recent months. Why is it important. China is adopting carbon-silicio batteries (sic), a technology that allows greater energy density without increasing the thickness of the device. The rest of the world maintains more conservative technologies even though Two years ago we warn of this impact. The context. Chinese brands have opted to solve one of user’s biggest headaches: autonomy. With larger screens, more frequently soda and applications that consume more energy, including Local generative AIThey need more capacity. 6,000 mAh or more mobiles already represent 35% of the Chinese market, compared to 9% of a year ago. OnePlus leads with the greatest average capacity thanks to Your Ace series, exclusive to China. There is a revealing pattern: brands such as Honor, Huawei and Vivo launch models with larger batteries specifically for the Chinese domestic market. But their global versions maintain minor capacities. Why does this happen? Because China is its test laboratory: SIC batteries certifications are more agile there. In China you can try that technology before facing the expensive and slow western approval processes. It is cheaper to try at home than to risk out with a new technology. And now what. China will maintain this short -term advantage while Western brands wait for SIC technology to mature. The gap will be reduced when more manufacturers adopt large batteries as a global differentiation factor, and not only in China.

The almost instantaneous load batteries and a shelf life close to eternity are taking shape. Thanks to quantum physics

by

Integrated circuits containing all our electronic devices, Solar panelsmagnetic resonance machines, The lasers or the atomic watches that allow the human being to measure time with an unprecedented precision would not be possible without the knowledge he has given us Modern Quantum Theory. And, of course, without this model we would not have Quantum computers. Objectively, and it is not at all an exaggeration, quantum physics is present in much of modern technology. During the last five years several research groups, such as the PSL Research University (University of Recherche Paris Sciences et Lettres), which resides in Paris (France), or that of the University of Pisa, in Italy, have tried to use the basic principles of quantum mechanics to point A new generation of batteries. And the results are getting little by little. This is its starting point: they pursue to use overlap, entanglement and superabsorption to tear down the limitations that electrochemical batteries currently impose. The quantum storage of energy is an ideal that is increasingly closer The main difference between quantum batteries and conventional electrochemicals is that the latter depend on chemical reactions, while quantum devices seek to store energy in the quantum states of some particles, such as, for example, photons. It seems complicated, and it is, but the really important thing for users is that quantum batteries on paper can be loaded almost instantaneously, they will have a much higher energy density, and, in addition, their degradation will be minimal as the load cycles pass. Quantum batteries can store energy in a superposition of multiple energy states simultaneously It sounds wonderful. So much, in fact, that seems science fiction. However, it is very important that, as we have just seen, let’s not overlook that their principle of operation will be, if they finally come to fruition, very different from that of conventional electrochemical batteries. Existing theoretical proposals argue that quantum batteries They can store energy in an overlap of multiple energy states simultaneously, which should allow them to deliver a much greater energy density. In addition, your theory load will be much faster, even almost instantaneous, due to the collective quantum effects of the quantum units that make them up. The most amazing thing in this field is that the higher the capacity of the quantum battery, the faster it will load. It is an intuitive characteristic, it is true, but it is possible precisely thanks to the collective quantum effects I just talked about. However, this is not all. And it is that on paper the degradation that these batteries will experience during energy transfer will be minimal, so your useful life will be much greater than that of conventional batteries. Perhaps, even, almost eternal if we compare it with the longevity of the human being. So far all the work that researchers had carried out in this area had condensed in purely theoretical models, but this panorama has just changed. And it is that several scientists from the universities that I have mentioned in the second paragraph of this text have published an article very interesting in which they propose How to make a quantum battery. Your idea is to use superconductor circuits produced with materials that exhibit essentially zero resistance at low temperatures. They have not yet manufactured anything, so it is evident that the hardest work, the experimental, is still pending. But there is no doubt that this proposal invites us to tie the future of quantum batteries with reasonable optimism.

To batteries, it does not need to recharge and save millions of liters of diesel

While Europe looks with sweet eyes on Hydrogen train and In Argentina they already presume their solar trainAustralia boasts of her brand new electric train. Wait, how “electric train” when that exists for decades and It is called Ave? Because the Australian train has an important nuance: it works with batteries and is not connected to the catenary. The result? An “infinite train” manufactured with racing technology. And with a mission: save a lot of money in diesel. The ‘Infinity Train’. Mining in Australia is a huge business And companies invest to improve their infrastructure, thus being more competitive and efficient in every way. Fortescue (how difficult it is not to write “Fortesque” as in ‘Medievil‘) is one of those companies, and just announce who have completed the pilot trip of their “intinifo train.” Driven only by its battery system and without being connected to the current, this ‘Intinity Train’ has completed a trip of about 1,100 kilometers, and the most impressive thing is that it will have to do another 1,100 kilometers back without having to recharge. In fact, the idea is to make constant round trips without going through a plug. His trick is not called Solar panels Not anything like that: it’s called regenerative braking. Formula braking 1 AND. In 2022, Fortescue acquired 100% of Williams Advanced Engineering, a British company founded as a split of the Williams team of Formula 1, but focused on the creation of High performance batteries for formula E. The purchase was closed for 223 million dollars and the objective was Accelerate decarbonization in the company’s mining operations. One of the keys to Formula E, which also applies to the Formula 1 battery system, is the generation of electric power thanks to braking. It is like a dynamo that generates electricity with the engine in reverse, and in the case of ‘Infinity Train’, it is a tremendously magnified process. A huge asterisk. Because here the trick is that the round trip from Perth to the Pilbara region makes it loaded with materials, increasing the weight of the train and maximizing regeneration in braking. But, in addition, it is a route with a slope down. The slope on the road to the mines to the port is 600 meters, so the train has more than 1,000 kilometers to, with up to 34,000 tons of iron from the mines, generating electricity that compensates for the expense it can do. The return path makes it downloaded and ‘strip’ of that energy that has filled the batteries so as not to need an external load nor the support of the catenaries. And start again: they return to load the train, go downhill up loading their batteries and then climb the energy generated. The matter of money. In a huge continent and with the complicated terrain to install catenaries, it is a solution that has all the way, but the limitation is more than evident: the technology of this train can only be applied in situations as specific as that of long journeys in which the phase of being loaded with materials is done downhill. In other situations, it seems more complicated. But well, the company’s intention is to electrify its more than 50 transport trains for 2030 with the aim of reducing its emissions and, in addition, saving What Diesel costs. It is difficult to get the idea of ​​magnitude, but They speak to cut 82 million liters of fuel per year and reduce 11% of its annual CO₂ emissions if they electrify the train network. Electrifying the mines. From the company they affirm that this technology can be exported to everyone, and in the end it is another step in the MODERNIZATION OF MINES. It is precisely in this work environment that the electrification It seems very necessary not only to reduce emissions and that companies meet their objectives, but to improve the health of workers. In recent years we are seeing Betting for electric trucks and even automatedand the ‘infinite train’ adds to the trend, but with the great point against that it is a possible vehicle in extremely concrete situations.

You already know how to turn CO2 into electricity and batteries

The new space race will not end until someone mount a self -sufficient colony on Mars, provided A company of such caliber Be available to our hand. For now, the Chinese Academy has been investigating how to generate and store energy without more raw material than the one that offers In situ The red planet. Convert the Martian atmosphere into electricity. The University of Science and Technology of China (USTC) has designed A pioneering system to feed the future human bases of Mars with energy from its own atmosphere. According to the study published in Science BulletinChinese thermal and energy engineers started from the Brayton cycle, on which the land gas turbines are based, but replacing noble gases such as xenon with the gases of the Martian atmosphere, dominated in 95% by carbon dioxide. When using a available fluid In situthe circuit can be filled after any leak and avoids the logistics nightmare of having to send tons of gas packaged from the earth. But the most surprising thing is that it would achieve a conversion efficiency of up to 22%. Take advantage of the atmosphere to store it. In addition to the Brayton generator that breathes CO2, another team from the same university He designed a battery of lithium-carbon dioxide (Li-Co2) that uses the CO2 of the atmosphere of Mars as an active discharge agent. It is nothing more than a proof of concept, but in laboratory conditions at 0 ºC, the cells of this battery reached an energy density of 373 Wh Kg⁻¹ and a durability of 1,375 hours, the equivalent of two marian months. It could be combined with solar panels, burning CO2 at night or during dust storms, as a solution the intermission of solar energy. Technology is similar to Lithium-Aire batteries, only instead of air, absorb the CO2 of the atmosphere and release energy to feed rovers and helicopters. It would be necessary to try it under variable pressure, radiation and fine dust that sneaks into all Martian mechanisms to approve. China hopes to make history on Mars with Tianwen-3. China’s space program goes at a vertigo speed and these theoretical concepts could be tested on Mars in robotic missions before what we expect. The Tianwen-3 probe of the CNSA Space Agency will mark the next landing of the Asian country on Mars. With a launch planned for 2028, it is the mission that expects to bring to the earth the First Martian soil samples after the cancellation of Mars Sample Return of the NASA. Whether in this or any next robotic mission, seeing a closed, compact and filling generator running on Mars next to a CO2 -based storage system would be a giant jump towards that hypothetical future in which the human being will be a multiphenetary species.

We promised them happy with the 7,000mah batteries. But Android is still Android

by

I have been able to try the Realme GT 7one of the first phones in the market (generalist, no gaming) with 7,000mAh battery. A full -fledged mobile with a battery whose duration is good, but not superlative. The point is that this is not the first time something like that happens to me. I have tried mobiles with 4,500mAh batteries that lasted a lot more than others with 5,000Mah. Mobile with 5,000MAH with completely disparate durations, and then we have Apple with a 4,600mAh battery that lasts more than some much larger. Not everything is the ability. Welcome is the ability. Between 7,000mah and 5,000mah I have it clear: big horse. A battery with greater nominal capacity, to equal optimization and consumption of the components, is a battery aimed at having a longer duration. A clear example is the Samsung Galaxy S25 Edge With its 3,900mah battery. Miracles do not exist and, with that capacity and the screen of a Galaxy S25+I was destined to have a battery that lasts little. Android is very Android. Android is a relatively free system, and this has as many advantages as inconvenience. There is nothing more efficient at an energy level than an AOSP ROM, based on “Pure Android” and with hardly any background processes. The issue is that manufacturers want to put their icing: customization layers. Although they provide added value, starting to build on Android is not simple, and adding both applications and extra processes, sometimes, does not work out. If a version is not optimized, it will devour resources, have the physical battery that the device has. There are even more elements. To the optimization that each manufacturer has to do in the system if you want the ROM to work well, you have to add that each phone element (screen, modem, Bluetooth, Wifi), has its associated controllers. A bad optimization or adjustment in the software that manages basic hardware elements can translate into triggered consumption. And, beyond optimization, hardware elements themselves can consume more or less. There are more or less efficient screens, there are more or less efficient processors, thermal management … The cocktail to create a mobile with a battery that lasts what must last is complex. The solutions. Sometimes, it is best to admit that there is no solution. If your mobile lasts little because milliamps are missing, there is no way out. In the opposite case, there is hope. If a telephone has a brutal battery, but it does not last enough, it is necessary to know the manufacturer to work in an update that solves it. It is not something, unfortunately, too common. But it is neither the first nor the last time that a phone does not work as fine in launch and, within a few weeks, it all starts stabilizing. In fact, this is not just an Android problem, although the system is more prone to these instabilities in the battery. I still remember The terrible battery of the iPhone 12 Pro. Yes, he had “only 2.815mah”, but the iPhone 13 pro lasted much more with 300mAh more. Super -healing problems, a total (health) capacity that touched 80% in just one year of use … Image | Xataka In Xataka | Save battery on your mobile: 28 things that increase their consumption on Android or iPhone and you can avoid

The contradiction that solves the bottleneck of solid state batteries

by

Lithium ion batteries carry decades fulfilling its role on day -to -day devices. They are still very valid for mobile, consoles and other small devices, but the arrival of the electric car has promoted a change. The industry is looking at some solid state batteries that have become In the best asset For car electrification. Promise much older autonomiesa longer life, faster loads, lower weight and greater security. There are many companies like Huawei, Samsung, Sling either Fordamong others, investigating the development of these batteries And, although marks like BMW don’t want to hear anything about them At the moment, others such as Mercedes have begun to implement them in test models. And the Technical University of Munich believes having found the key to accelerating the development and adoption of solid state batteries: a new material that “dopa” lithium and lithium conducts its ions 30% faster than any other material. Doping lithium to accelerate solid state batteries Despite all its promises, solid state batteries have faced historically a key bottleneck: The low ionic conductivity at room temperaturewhich limits loading and unloading speed. In liquid electrolytes, lithium ions move easily, but in solids, the crystalline network and interionic forces They hinder That movement, slowing down the process. Therefore, much of the current research It focuses on finding materials that allow a more efficient ionic migration The Energy Research team of the TUM has published a study in which it is detailed how they have achieved that improvement in conductivity. The key has been a new material that achieves the greatest ionic conductivity ever registered in this field thanks to eliminating part of the lithium and replacing it with Scandio. This substitution generates holes in the crystalline network that are called “vacancies”, and by reducing that density, the movement of lithium ions is freer. Therefore, conductivity increases significantly. According to his tests, this new compound of lithium, antimony and scandio drives ions 30% faster That any other material known to date and Professor Thomas F. Fäsler, team leader, points out that the material not only allows that higher speed, but also an improvement in thermal stability. “By incorporating small amounts of Scandio, we have discovered a new principle that could serve as a model for other elementary combinations,” says Fäsler. “The materials that conduct both ions and electrons are especially suitable as additives in the electrodes and, due to their promising practical applications, we have already requested a patent to develop it,” he continues. Apart from this new material, during the investigation they realized that there are other substances that work well with other materials. Jingwen Jiang is one of the authors of the study and states that his combination “is based on lithium and antimony, but the same concept can be easily applied to lithium and phosphorus systems. In previous record it was based on lithium and sulfur and required Five additional elements for optimization, but we have only needed scandio as an additional component. ” He also states that his discovery could have broader implications to improve conductivity in other materials, but Fäsler confesses that although they are optimistic, “many tests are still needed before the new material can be used in battery cells.” Therefore, it seems that There is time for these solid state batteries to impose themselvesand it is also logical to think that, little by little, they will optimize them much more. At the moment the interesting thing is so much that they have improved that ionic communication and, above all, that they have done so simplifying the processes with simpler compositions.
