What is the hidden safety of 3C lithium-ion battery?

3C lithium ion battery has the following safety hazards: 1. Material 3C lithium ion battery's temperature is overheated, the active material of the cathode material will automatically decompose, and the electrolyte will oxidize at the same time, and a lot of heat will appear, which will further increase the battery temperature and affect the battery. The stability of the battery; when the temperature is too high, the negative electrode of the battery will have an exothermic reaction with the electrolyte, causing the battery to overheat and burn and explode, which is dangerous. 2. Process The manufacturing process of 3C lithium-ion battery should be standardized and rigorous. During the manufacturing process, the battery material quality, slurry uniformity, coating, cutting control, etc. are very important, each process will affect the battery Safety performance and quality. The manufacturing process of 3C lithium ion battery can be divided into positive and negative electrode material mixing, coating, cutting, punching, rolling, filling electrolyte, forming, dividing, sealing, assembling and so on. 3. In the process of using 3C lithium-ion battery, if the method is not appropriate, it is very likely that the battery will have a safety hazard. For example, when charging is overcharged and overdischarged, long-term charging will cause the battery to swell and expand. Once the internal temperature exceeds the set value, the battery may be short-circuited in extreme cases, which may cause the battery to burn or explode. Fourth, the testing of 3C lithium-ion batteries is not standardized, which will cause inferior batteries with unstable performance to flow into the market, making batteries with inherent safety hazards even more unsafe. Therefore, standardizing the test process, selecting a suitable battery test module, rigorously recording the test results, and repairing and redoing defective batteries are the focus of 3C lithium-ion battery testing.
