What are the manufacturing processes of lithium batteries? How to maintain

What are the manufacturing processes of lithium batteries? 1. Ingredients: Use a special solution and a binder to mix with the powdered positive and negative active materials, stir and average them at a high speed to form a slurry of positive and negative materials. 2. Coating: The prepared slurry is evenly coated on the surface of the metal foil, and dried to form positive and negative pole pieces respectively. 3. Assembly: Place the positive electrode diaphragm and negative electrode diaphragm in the order from top to bottom. The battery pole core is made by winding, and the battery assembly process is completed after injecting electrolyte and sealing. 4. Formation: Use special battery charging and discharging equipment to conduct charge and discharge detection of finished batteries, and test each battery. 5. Divided capacity: that is, qualified finished batteries will be screened out and ready to leave the factory. 6. The above is only a rough outline, and there are rolling, slitting, cutting, winding, baking, liquid injection, sealing and so on. The lithium battery is maintained at a suitable temperature to prevent heat and cold. When idle, lithium batteries usually do not have safety accidents. The purpose of daily maintenance is to place the lithium batteries in a suitable environment, thereby delaying the aging of the batteries. In fact, one of the parameter designs of lithium batteries is the appropriate temperature. Relatively speaking, lower temperature is not a big problem, but if it is placed at a higher temperature, as the saying goes, the thing is extremely reversed, and safety problems will also occur. The idle state we are talking about is only in terms of the normal environment. If the lithium battery is placed in water or close to the fire source, it will be out of the topic of maintenance. Then, what is to be done in a normal environment? The water side is moisture-proof and the hot side is sun-proof. Therefore, the appropriate environment for daily maintenance of lithium batteries should be four words: ventilation and cool. These four words should be followed regardless of whether the lithium battery is left unused independently or ready for use in electrical appliances.
