Working principle and assembly process of lithium battery
Tools/Materials
Cathode material
Negative material
separator paper
steps/methods
1. Pulping:
Use a special solvent and a binder to mix with the powdery negative electrode active material respectively, and after high-speed stirring, make a slurry-like positive and negative electrode material.
2. Coating film:
The prepared slurry is uniformly coated on the surface of the metal foil, dried, and respectively made into positive and negative pole pieces.
3. Assembly:
According to the order of positive electrode sheet-diaphragm-negative electrode sheet-diaphragm from top to bottom, it is wound to form a battery pole core, and then the battery assembly process is completed after injecting electrolyte and sealing. Finished battery.
4. Formation:
The traditional battery charging and discharging equipment is used for charging and discharging tests on the finished batteries, and each battery is tested, and the qualified finished batteries are screened out to be shipped.
Notes
The process technology of lithium-ion batteries is very strict and complicated, here is just a brief introduction!
