Critical safety risks of 3C lithium batteries

The key safety risks of 3C lithium batteries are as follows: 1. Raw materials. When the lithium 3C rechargeable battery is at a high temperature, the active material of the battery's positive electrode material will automatically dissolve, and the lithium battery electrolyte will oxidize in the air, causing a lot of heat, which further increases the battery temperature and harms the reliability of the rechargeable battery; The positive electrode material of the battery will react chemically with the electrolyte of the lithium battery, causing the rechargeable battery to ignite over temperature and explode, which poses a certain risk. 2. Process lithium battery requires strict standards in 3C manufacturing. In manufacturing, the quality of lithium battery materials, the uniformity of the slurry, the automatic control system for sizing, and cutting into slices are all very critical, and every process flow is critical. It will endanger the safety factor and quality of rechargeable batteries. The processing process of lithium battery can be divided into the wrong material of positive and battery cathode materials, sizing, cutting, shearing, rolling, adding lithium battery electrolyte, forming, dividing, nailing, installation, etc. 3. Application. In the whole process of the application of 3C lithium battery, if the method is not suitable, it is very likely that the rechargeable battery will be a safety risk. For example, in the whole process of battery charging, overcharging and loss of power, long-term battery charging will cause the rechargeable battery to swell. Once the internal temperature exceeds the preset value, it is likely to cause a short circuit failure of the rechargeable battery under extreme conditions, which may cause the rechargeable battery to ignite or occur. explosion. Because the 3C lithium battery test is not standard, counterfeit and inferior rechargeable batteries with unstable characteristics are injected into the sales market, making their own rechargeable batteries with safety risks even more unsafe. Therefore, the standard test procedure, selecting the appropriate rechargeable battery test control module, rigorously recording the test results, and repairing the quality of the rechargeable batteries are the key to the 3C lithium battery test.
