Analysis of lithium-ion battery technology and classification of lithium-ion battery manufacturers

The lithium-ion battery technology of lithium-ion battery manufacturers is very strict and complex. Here are some important processes.

Lithium-ion battery manufacturer

1. Preparation of Electrode Paste

It is mainly used to mix electrode active materials, binders, solvents, etc., and stir evenly to form a slurry.

2. Coating

The slurry prepared in the first step is uniformly coated on a collector (aluminum foil or copper foil, etc.) with a specified thickness, and the solvent is dried.

3. Plate die cutting

Press the pole piece produced in the previous step into the specified size and shape

4. Lamination

The positive and negative plates are assembled with the separator. When the glue is done, the core is formed.

5. Assemble the soft pack battery

Put the magnetic core produced in the previous step into the porous aluminum-plastic film, complete the top sealing, side sealing, etc. (it can also leave the injection port) to form a liquid-free soft pack battery.

6. Liquid injection

A certain amount of electrolyte is injected into the inside of the soft tank (of course, the battery should be baked and injected in a low humidity environment). If the moisture content is too high, it is not good

7. Battery Seal

Extract the gas from the battery and seal it in a vacuum

Classification of Lithium Ion Batteries

1. Metal lithium ion battery: Generally speaking, metal lithium ion battery uses manganese dioxide as the positive electrode material, lithium metal or its alloy metal as the negative electrode material and non-aqueous electrolyte solution.

Detailed knowledge of the process flow, advantages and disadvantages, classification, etc. of lithium-ion battery manufacturers to produce lithium-ion batteries(Lithium - Ion Battery Equipment)

2. Lithium-ion battery: Lithium-ion battery generally uses lithium alloy metal oxide as the positive electrode material, graphite as the negative electrode material, and non-aqueous electrolyte.
