What is the safety risk of 3C lithium battery?

　　1. Raw Materials

　　In our daily life, we commonly use 3C lithium battery in the case of charging will produce high temperature, in which the battery's positive electrode active material will automatically dissolve, lithium battery electrolyte will air oxidation, causing a lot of heat, further improve the battery temperature, harm the reliability of the rechargeable battery; At high temperature, the cathode material of rechargeable battery will react with the electrolyte of lithium battery, resulting in overtemperature ignition and explosion of rechargeable battery, and there is a certain risk.

　　2, process

　　Strict standards are stipulated in the 3C manufacturing of lithium battery. In the manufacturing, the quality of lithium battery materials, the symmetry of slurry, sizing and automatic control system of cutting are very critical, and every technological process will harm the safety factor and quality of rechargeable batteries. The production process of lithium electric can be divided into positive, battery anode material mis-material, sizing, cutting, shear pressure, roll pressure, lithium battery electrolyte, into, capacity, nail, installation, etc.

　　3, the application

　　In the whole process of application of 3C lithium, if the way is not feasible, it is also likely to make rechargeable batteries have safety risks. For example, in the whole process of battery charging, excessive charge loss, long-term battery charging will make the rechargeable battery expansion, once the internal temperature exceeds the preset value, the extreme condition is likely to cause the rechargeable battery short circuit fault, and then cause the rechargeable battery ignited or exploded.

　　Due to the non-standard testing of type 3C lithium, fake rechargeable batteries with unstable characteristics are injected into the sales market, which makes their own rechargeable batteries with safety risks more unsafe. Therefore, the key of 3C lithium battery experiment is to select the standard experimental procedure, select the appropriate rechargeable battery experimental control module, strictly record the experimental results, and repair the rechargeable battery with any quality problems.
