What are the reasons for the explosion of lithium batteries

1. Temperature. There are many factors that affect the safety of lithium batteries. Among them, battery materials have a major impact on the safety of lithium batteries, because battery materials generally have thermal activity. When the temperature of the battery continues to rise, many thermal reactions will occur inside it. When the heat cannot be dissipated in time, it is easy to cause battery safety accidents. Therefore, the choice of lithium battery positive and negative materials has an important impact on battery safety performance. 2. Manufacturing process. The manufacturing process of the battery is also an important factor that affects the safety performance of the battery. Among them, there are three most important factors, namely the positive and negative electrode capacity ratio, slurry average degree control, and coating quality control. During use, overheating caused by high current (external short circuit, internal short circuit) causes an explosion; breaking may also expose the unstable negative electrode (with lithium deposits) after charging to the air and cause a large amount of heat / or insufficient negative capacity; overcharge/ Overdischarge can also cause the explosion of the lithium battery.
