Explaining the production process of lithium ion battery.energy storage battery 48v lithium ion battery

release time:2023-03-16 Hits: Popular:AG11 battery

　　In the process of charging and discharge, Li+ is embedded and dehydrated between the two electrodes: when charging, li+ is dehydrated from the positive pole, the electrolyte is embedded in the negative electrode, and the negative electrode is in the lithium rich state; the opposite is the opposite when discharging.

　　The positive materials of lithium batteries are lithium cobaltate LICOO2, triangular materials NI+Mn+CO, lithium manganate LIMN2O4 plus electrical and adhesive, coated on aluminum foil to form positive electrodes. The agent is applied to the copper foil base, and the more advanced negative electrode graphite particles have been nano -carbon.

　　1. Purching: Mix it with powder -like positive and negative active substances with special solvents and adhesives. After mixing, it is made into a slurry -like positive and negative electrode substance.

　　2. Coating film: The positive and negative polar slurry is evenly coated on the surface of the metal foil by automatic coating machine. After automatic drying, it is automatically cut into a positive pole film.

　　3. Pretending: According to the top -to -bottom order of the positive chip -diaphragm — negative film -septum from top to bottom, the process process is injected into the electrolyte, sealing, positive and negative polar ear welding and other processes, that is, the assembly process of the battery is completed to make the finished battery.

　　4. Turn into: Putting the product battery test cabinet for charge and discharge test, screen out the qualified finished battery, and leave the factory.
