What factors should be paid attention to for the safety of power 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, new energy vehicle fire incidents have occurred frequently, and the survey results show that most of them are related to power lithium-ion batteries. Therefore, the safety issue of power lithium batteries has become a hot topic of discussion. The safety influencing factors of lithium batteries, how do the 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 rises, there will be a lot of liquid inside, which will not be lost when heated, which will easily lead to battery safety Accidents, so the choice of anode materials for lithium batteries has an important impact on battery safety functions. The second battery manufacturing process is also an important factor, which affects the safety function of the battery. The three most important factors are the cathode capacity ratio, slurry uniformity control, and coating quality control. This is the ratio of the cathode capacity to the use of the battery. Life, safety characteristics, to ensure the safety function of the battery, we must fully consider the positive and negative cycle characteristics of the battery and the positive capacity of lithium. The uniformity of the slurry directly affects the uniformity of the dispersion of the battery active material 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. At present, the application of lithium batteries is becoming more and more extensive, so it is necessary to improve the manufacturing technology of power lithium batteries to ensure the safety of power lithium batteries, thereby promoting the development of lithium batteries and related industries.
