1) The use of high-safety solid-state battery technology The biggest advantage of solid-state batteries is that the electrolyte is solid, and there is no danger of leakage, volatilization, or swelling. Its high mechanical strength can prevent lithium dendrites from penetrating and causing internal short-circuits, and can remove the negative The barrier between lithium and air can greatly improve safety performance, and then solve the problem of spontaneous combustion of lithium batteries. (2) Improve the BMS, the thermal management system level can solve the battery overcharge and overdischarge through continuous improvement of the BMS level, and improve the thermal management system can solve the battery overheating problem, and then solve the lithium battery spontaneous combustion problem. For example, the battery monitoring sensor is added, and the air cooling system is changed to water cooling. (3) Strengthen product supervision and accountability efforts. Strengthen the factory safety testing of battery products and car products, and improve accountability for incidents can significantly reduce manufacturers’ production problems. As much as possible to eradicate the spontaneous combustion of lithium batteries. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
