What is 3C lithium-ion battery and what is its harm

　　1. Material The active substance of 3C lithium-ion battery cathode material will be completely dissolved under overtemperature. The air oxidation of lithium ion batteries will cause widespread concern, further increase the battery temperature, and endanger the reliability of rechargeable batteries. When the temperature is too high, the potential of rechargeable battery will react with the chemical reaction of lithium ion battery electrolyte

　　2. The preparation process of 3C lithium ion battery, the quality of raw materials, the quality of raw materials in the manufacturing process, the uniformity of slurry, the size of slurry and the operation of chips are very important. Each process will affect the safety factor and quality of rechargeable batteries. The processing technology of 3C lithium-ion battery can be divided into cathode material, sizing, cutting, shearing pressure, rolling, lithium-ion battery electrolyte charging, capacitance, sealing, assembly, etc

　　3. In the whole application process of 3C lithium-ion battery, if the method is not suitable, the rechargeable battery may have a safety risk. For example, when the battery is charged, the battery will overcharge, the battery will charge for a long time, and the battery drum will rise. Once the internal temperature exceeds the preset value, extreme conditions are likely to lead to short circuit fault of the battery, and the rechargeable battery will ignite or explode.

　　4. The nonstandard detection of 3C lithium-ion batteries will lead to the unstable characteristics of counterfeit rechargeable batteries entering the sales market, making the safety risks of their own rechargeable batteries even more unsafe. Therefore, standard test steps, selection of compatible battery test package, careful recording of test results, and improvement of battery quality are the keys to 3C lithium-ion battery testing
