Yang Yusheng: Multiple Paths to High Safety of Lithium-Ion Batteries
Lithium-ion battery combustion is mainly triggered when the battery temperature rises to a critical threshold. The oxidizing cathode active material decomposes and releases oxygen, which reacts with combustible organic substances. The heat generated by this reaction further pushes up the temperature, leading to thermal runaway and eventually resulting in fire and explosion. According to the basic principle of the fire triangle, combustion cannot occur without heat, fuel, or an oxidizer. Therefore, improving the safety of lithium-ion batteries must target these three essential elements, and multiple technical approaches can be adopted.
