1. 18650 lithium battery is in use
Under the application of the 18650 lithium battery, if the operation is improperly used, it is likely to cause hidden safety hazards in the rechargeable battery. For example, if the battery charges is over -charging and lost power, the long -term battery charging will cause the rechargeable battery to swell. Once the internal temperature is higher than the preset value, it is likely to cause a short -circuit failure of the rechargeable battery under extremeization. Or an explosion accident.
Because the 18650 lithium battery detection is not standardized, the fake and inferior charging batteries with unstable characteristics are injected into the sales market, making it unsafe in rechargeable batteries with hidden safety hazards. Therefore, the standard experimental step is to select the appropriate charging battery experimental control module, the harsh record experimental results, and the maintenance of the rechargeable battery with the quality of quality is the key to the 18650 lithium battery experiment.
2. The raw materials of the 18650 lithium battery
In daily life, the 3C lithium battery that we commonly use will also generate high temperature under charging. Among them, the battery's positive active material will be fully dissolved automatically. The lithium battery electrolyte will oxidize the air, resulting in a lot of heat capacity, which will further increase the battery temperature , Harm the reliability of the rechargeable battery; at high temperature, the positive electrode material of the rechargeable battery battery will have a chemical reaction with the lithium battery electrolyte, resulting in overheating the rechargeable battery and explosion accidents. There is a certain risk.
3. The manufacturing process of the 18650 lithium battery
Lithium battery stipulates harsh standards in manufacturing. In the manufacturing, the quality of lithium battery materials, symptoms of the slurry, glue, and automatic control system for cutting are all important. It will endanger the safety performance and quality of the rechargeable battery. The process of lithium batteries can be divided into the wrong material of positive, battery positive materials, gel, cutting, shear pressure, roller pressure, adding lithium battery electrolytes, turning into, capacity, nailing, installation, etc.
