Recently, a domestic new energy vehicle company announced the use of a new type of polysilazane (PSZ) coating technology to improve the safety of power batteries. The material is resistant to high temperatures of more than 1000°C and can form a dense ceramic barrier in the early stage of battery thermal runaway to delay the spread of fire. Combined with AI algorithms to monitor battery cell temperature, voltage and other parameters in real time, the system can warn of potential risks 15 minutes in advance. The R&D team said that the technology has passed extreme tests such as acupuncture and overcharging, and plans to be installed in mass-produced models next year. Industry insiders analyzed that this move will promote the upgrade of electric vehicle safety standards and help the industry break through the "explosion anxiety".
