Improving the safety of lithium batteries can be approached from various aspects such as material research and development, battery design, production processes, battery management systems, and usage and maintenance. The specific methods are as follows: In terms of materials

Improvement of battery materials: research and development of positive electrode materials with higher thermal stability, high safety electrolytes, etc. For example, using positive electrode materials with good thermal stability such as lithium iron phosphate, compared to materials such as lith

Internal factors Thermal stability issue: Lithium batteries generate heat during the charging and discharging process, and when the internal temperature of the battery is too high, it may cause thermal runaway. For example, positive electrode materials may decompose at high temperatures,
