What factors are involved in the safety of lithium batteries? With the popularization of new energy vehicles, people's demand for power lithium batteries is becoming stronger and stronger. However, in recent years, there have been frequent fires in new energy vehicles, and most of the results of the investigation are related to power lithium-ion batteries. Therefore, the safety of lithium battery power has become a hot topic. How much affect the safety elements of lithium batteries, battery materials have an important impact on the safety of lithium batteries, because battery materials and heat are generally active, when the temperature of the battery continues to rise, there will be a lot of liquid inside, which will not be lost when heated, which is easy to cause the battery Safety accidents, so the choice of anode materials for lithium batteries has an important impact on battery safety functions. The second battery processing process is also an important factor that affects battery safety functions. The three most important factors are cathode capacity ratio, slurry uniformity control, and coating quality control. This is the ratio of cathode capacity to battery life. In order to ensure the safety function of the battery, the demand is negative cycle characteristics, and fully consider the acceptability of the battery and the lithium anode. The uniformity of the slurry directly affects the uniformity of the battery active material distribution on the electrode. The quality control of the coating is not very good, and it is very simple to cause a short circuit inside the battery. In addition, the thickness and uniformity of the coating will affect the insertion and release of the active material. Nowadays, the application of lithium batteries is more and more extensive, so we must improve the processing technology of power lithium batteries to ensure the safety of power lithium batteries, so as to promote the development of lithium batteries and related industries.
