Neural Networks Speed Up Search For Solid-State Battery Materials For Safer Electric Cars With Extended Range
Press Release – Skoltech So far solid-state batteries have not been adopted by carmakers, but EV developers are looking to capitalize on the technology before competitors. The new type of energy storage could improve fire safety and boost EV range by up to 50%. Researchers from Skoltech and AIRI Institute have shown how machine learning can speed up the development of new materials for solid-state lithium-ion batteries. These are an emerging energy storage technology, which could theoretically replace conventional Li-ion batteries in electric vehicles and portable electronics, reducing fire hazards and extending battery life. In the Russian Science Foundation-backed study, published in npj Computational Materials, neural networks proved capable of identifying promising materials for the key component of these advanced batteries — the solid electrolyte — as well as for its protective coatings. Like its conventional counterpart, the solid-state battery incorporates an electrolyte, through which ions carrying the electric charge travel from one electrode to another. While in a conventional battery the electrolyte is a liquid solution, its solid-state analogue, as the name suggests, relies on solid electrolytes, such as ceramics, to conduct lithium ions. So far solid-state batteries have not been adopted by carmakers, but EV developers are looking to capitalize on the technology before competitors. The new type of energy storage could improve fire safety and boost EV range by up to 50%. The problem is that none of the currently available solid electrolytes meets all the technical requirements. So the search for new materials continues. 'We demonstrated that graph neural networks can identify new solid-state battery materials with high ionic mobility and do it orders of magnitude faster than traditional quantum chemistry methods. This could speed up the development of new battery materials, as we showed by predicting a number of protective coatings for solid-state battery electrolytes,' commented the lead author of the study, Artem Dembitskiy, a PhD student of Skoltech's Materials Science and Engineering program, a research intern at Skoltech Energy, and a junior research scientist at AIRI Institute. Study co-author, Assistant Professor Dmitry Aksyonov from Skoltech Energy explained the role of protective coatings: 'The metallic lithium of the anode is a strong reducing agent, so almost all existing electrolytes undergo reduction in contact with it. The cathode material is a strong oxidizing agent. When oxidized or reduced, electrolytes lose their structural integrity, which can degrade performance or even cause a short circuit. You can avoid this by introducing two protective coatings that are stable in contact with the anode and the electrolyte and the cathode and the electrolyte.' Machine learning algorithms make it possible to accelerate the calculation of ionic conductivity, a key property both for electrolytes and for protective coatings. It is among the most computationally challenging characteristics calculated in screening the candidate materials. For protective coatings, the list of properties that are checked at various stages of material selection includes thermodynamic stability, electronic conductivity, electrochemical stability, compatibility with electrode and electrolyte materials, ionic conductivity, and so on. Such screening happens in stages and gradually narrows down the list of perhaps tens of thousands of initial options to just a few materials. The authors of the study used their machine learning-accelerated approach to search for coating materials to protect one of the most promising solid-state battery electrolytes: Li10GeP2S12. The search identified multiple promising coating materials, among them the compounds Li3AlF6 and Li2ZnCl4.

China hits solid-state battery milestone with Gotion's 0.2 GWh pilot line for safer EVs
Gotion, one of the world's largest electric vehicle (EV) battery manufacturers, has officially entered the all-solid-state battery race with the launch of its first experimental production line aimed to test and refine next-generation battery technologies. Unveiled during Gotion High-tech's 13th tech conference on May 17, the facility reportedly represents a major milestone in the shift toward safer, more efficient battery technologies that could define the future of electric mobility. Designed with a capacity of 0.2 gigawatt-hours (GWh), the newly built pilot line will produce Gotion's all-solid-state Gemstone battery cells, which are already undergoing real-world road testing in EVs and have shown promising results. The batteries deliver approximately 40 percent higher energy density compared to conventional lithium ternary cells, offering 350 watt-hours per kilogram (Wh/kg) or 800 watt-hours per liter (Wh/L). This, according to the Chinese company, makes them a promising alternative for EVs. Pan Ruijun, Gemstone project research and development head, revealed that the entire production setup uses domestically manufactured equipment. He emphasized that the batteries have already been installed in vehicles and tested on the road. This, according to Ruijun, not only reduces the dependency on foreign suppliers, but also underscores China's accelerating leadership in battery innovation. He further pointed out that after a full year of performance validation, individual Gemstone cells have achieved a 150 percent increase in capacity, though exact figures were not disclosed. Gotion, in which Volkswagen holds a 24.45 percent interest, also highlighted that the batteries passed rigorous tests including pin-prick, hot-box, overcharge, and crush stimulations. The outcomes reinforced their promise as a safer alternative to traditional lithium-ion (Li-ion) cells, which are prone to overheating and thermal runaway. "This means that the human imagination of this ultimate battery is finally within reach," Ruijun stated. While no official mass production date was provided at this year's conference, the EV battery giant previously stated that small-scale production and vehicle integration could begin in 2027, with full-scale manufacturing expected by 2030. That timeline aligns with similar goals announced by major competitors. CATL and BYD, two other leading Chinese battery makers, have also outlined plans for limited deployment of solid-state batteries by 2027. However, despite growing industry excitement, significant hurdles remain for the commercial rollout of the solid-state technology. The company revealed that these include scaling up manufacturing, ensuring long-term material stability, and driving down production costs. Meanwhile, the Chinese government recently introduced stricter safety standards for EV batteries, set to take effect on 1 July next year, that aim to further improve cell safety. Yet, Gotion's transition to pilot-scale production serves as a strong indication that the solid-state battery industry is progressing beyond theoretical development and entering the early stages of practical implementation. With a 3.5 percent share of the global EV battery market as of Q1 2025, ranking it sixth worldwide according to SNE Research, the company is now positioning itself at the forefront of the solid-state revolution. If it meets its projected goals, the Gemstone line could play a central role in reshaping battery architecture and accelerating the transition to cleaner transportation.
