What are the main processes for battery 18650 genuine production?
As we all know, the production process of battery 18650 genuine packs is quite complicated. After all, the safety performance of lithium-ion battery products is directly related to the life and health of consumers. Naturally, the performance, accuracy, stability and automation level of equipment are highly concerned in the production and manufacturing of lithium batteries. Require. The reason is that the preparation of positive and negative electrode slurries for battery 18650 genuine packs includes a series of processes such as mutual mixing, dissolution, and dispersion of liquids and liquids, liquids and solid materials, and is accompanied by changes in temperature, viscosity, environment, etc.
Step 1 - Electrode Slurry Preparation
Mainly, the electrode active materials, binders, solvents, etc. are mixed together and thoroughly stirred and dispersed to form a slurry.
Step 2 - Coating
Low temperature lithium iron phosphate battery 3.2V 20A -20℃ charging, -40℃ 3C discharge capacity ≥70%
Evenly apply the slurry prepared in the first step to the current collector (aluminum foil or copper foil, etc.) with a specified thickness, and dry the solvent.
Step 3 - Pole piece punching
Cut the pole piece made in the previous step into the specified size and shape.
Step 4 - Lamination
Step 5 - Assemble the Soft Pack Battery
Put the pole core produced in the previous step into the aluminum-plastic film that has been punched and complete the top sealing, side sealing, etc. (leaving a hole for liquid injection) to form a soft-pack battery that has not been filled with liquid.
Step 6 - Injection
Inject the specified amount of electrolyte into the soft-packed battery cell. Of course, the battery core must be baked and filled with liquid in a low-humidity environment. Excessive moisture content is not good.
Step Seven - Battery Sealing
The gas inside the cell is extracted and sealed in a vacuum environment.
