How to improve the safety of batteries?

In terms of the safety realization of power lithium-ion batteries, from the perspective of battery companies, what specific improvements should be made to truly prevent this gray rhino. Gaogong Lithium has made in-depth exchanges with industry experts and upstream and downstream companies in the industry chain. The following suggestions: First, in the choice of materials, the choice of core materials will directly affect the safety of the final battery cell product. A technical person in charge of Rongbai Technology explained to Gaogong lithium battery that the safety of the battery cell depends largely on the core material, especially for the high nickel ternary system, the metal foreign matter content, residual lithium and PH value of the cathode material , It will have a great impact on the safety performance of the battery. The second is to do a good job in safety redundancy and monitoring and early warning in the design of batteries, modules, packs, and process settings. In the design process, the first is to ensure the chemical stability of the battery cell, select stable materials, and pass strict evaluation and test its stability; in the module part, the structure protects the battery cell from impact. The third stage is pack. In addition to physical protection measures, the key is to diagnose the battery cell module through the BMS, monitor the occurrence of abnormalities, and predict possible problems, so as to control the problems. The third is to fully verify the test and verification before mass production. In fact, this is also the biggest problem currently facing the domestic power lithium-ion battery field. On the one hand, product replacement is rapid, on the other hand, testing and verification takes time and labor and the lack of relevant design reference experience has led to frequent accidents in recent years.
