The main hazards of 3C product lithium ion battery are:
1、 Materials
The active material of 3C product lithium ion battery cathode material will be completely dissolved under overtemperature. The air oxidation of lithium battery will attract a lot of attention, further increase the battery temperature and endanger the reliability of rechargeable battery. When the temperature is too high, the potential of the rechargeable battery will react with the chemical reaction of the lithium battery electrolyte.
2、 Processing process
The process of preparing 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 chip are very important. Each process affects the safety factor and quality of rechargeable battery. The processing technology of 3C lithium ion battery can be divided into cathode material, sizing, cutting, shear pressure, rolling, lithium battery electrolyte, capacitance, sealing, assembly, etc.
3、 Use
In the whole application process of 3C lithium-ion battery, if the method is not appropriate, the rechargeable battery may have safety risks. For example, when the battery is charged, the battery will be overcharged, the battery will be charged for a long time, and the battery drum will rise. Once the internal temperature exceeds the preset value, the extreme situation is likely to lead to battery short-circuit fault, and the rechargeable battery will ignite or explode.
4、 Testing
The non-standard detection of 3C lithium-ion batteries will lead to the unstable characteristics of fake and shoddy rechargeable batteries entering the sales market, making the safety risk of their own rechargeable batteries more unsafe. Therefore, the standard test steps, selecting a compatible battery test pack, carefully recording the results, and improving the battery quality of the version are the key to the detection of 3C lithium-ion batteries.
3C product lithium ion battery solution:
In order to deal with the possible safety risks of 3C lithium-ion battery, the safety factor of metal electrode and lithium battery electrolyte can be improved, the direct contact between metal electrode and lithium battery electrolyte can be prevented, and the reliability of rechargeable battery can be improved. Secondly, improve the safety maintenance design of 3C lithium-ion battery, ensure the equipment of battery protection board, select thermal closed diaphragm, set charging valve, replace and maintain power circuit, power circuit and thermal fuse, so as to improve the safety factor of rechargeable battery. Third, the battery detection group can select high current spring micro needle and capacitive touch group. The high current shrapnel microneedle module can carry a high current of 50a, the connection is stable and reliable, and has good adaptability in the pitch field. The average service life can reach more than 20W, and the detection compatibility of 3C lithium-ion battery is good.
