On March 12, 2025, Tesla and the Chinese Academy of Sciences jointly announced that they had successfully developed a third-generation polysilazane (PSZ) battery pack protective coating through an AI material computing platform. In simulation tests, the material showed the characteristics of maintaining structural stability at extreme high temperatures of 1600°C, with a 40% increase in heat resistance compared to traditional materials, which can effectively slow down the spread of thermal runaway of electric vehicle batteries. The team used machine learning to analyze more than 20,000 sets of organosilicon compound databases worldwide and finally locked the molecular structure. It is reported that BYD has purchased the coating technology for the upgraded version of the "blade battery", and the new solution can reduce the weight of the battery pack by 15%. Industry analysts predict that the global market size of organosilicon materials for new energy vehicles will exceed US$8 billion in 2025.
