Causes of the explosion of lithium batteries

Will lithium batteries explode? There are many reasons for lithium batteries to explode, which can be roughly divided into external short circuits, internal short circuits, and overcharging. Under normal circumstances, the north and south poles of a lithium battery will definitely not touch each other, so the battery manufacturer will place a separator between the north and south poles. High-quality diaphragm paper, when the internal temperature of the battery is high, it will block the tiny holes and stop the electrochemical reaction, causing the current to drop suddenly and the temperature slowly to prevent explosion. But if the diaphragm breaks under the influence of various factors, all the energy in the battery will rush to the electrolyte, and the electrolyte itself is an unstable chemical substance. After absorbing too much energy, it will become hot or even catch fire. How to maintain lithium batteries 1. Lithium batteries should be stored in a cool, dry, and safe environment, and can be stored in a clean, dry, and ventilated environment with a temperature of -5~35°C and a relative humidity of not more than 75%. Note that storing the battery in a high-temperature environment will unpreventably damage the quality of the battery. 2. Prevent placing lithium batteries near heat sources, open flames, flammable and explosive gases and liquids, so as to avoid battery leakage, heat generation, smoke, fire, and explosion. 3. If the lithium battery needs to be stored for a long time (more than 1 month), the battery power should be maintained at 30%~50% of the nominal capacity, and the battery should be refilled for 1-2 hours per month during the storage period. 4. The battery should be packed into the box during transportation. During transportation, it should be prevented from violent vibration, impact or kneading, and to prevent sun and rain. It can be used to transport vehicles, trains, ships, airplanes and other vehicles. 5. During the storage of lithium batteries, metal objects should be prevented from entering the battery box to avoid battery leakage, heat generation, smoke, fire, and explosion. 6. If the lithium battery is used in an environment higher than the normal operating temperature, that is, 35°C, the battery power will continue to decrease. If you have to charge the lithium battery at this temperature, the damage will be even greater. Therefore, keeping the operating temperature as suitable as possible is a good way to extend the service life of lithium batteries. 7. In order to make full use of lithium batteries, you have to use them frequently to maintain the flow of electrons. If you don't use lithium batteries often, please remember to end the charging cycle of lithium batteries once a month and do a power calibration, that is, deep discharge and deep charge. 8. Shallow discharge and shallow charge are more beneficial to lithium batteries. Only when the product's power module is calibrated on time for the lithium battery, can deep discharge and deep charge be necessary. Therefore, do not get stuck in the process of products using lithium power supply, everything must be convenient first, charge at any time, and do not worry about the impact on life.
