The manufacturing process of lithium batteries is as follows:
1. Preparation of electrode suspension, mainly by mixing electrode active materials, binders, solvents, etc. and stirring carefully after dispersion. , a slurry forms.
2. Coating, evenly apply the slurry prepared in the first step to the current collector (aluminum foil or copper foil, etc.) with specified thickness and dry the solvent.
3. Punching the pole piece, punch the pole piece produced in the previous step into the specified size and shape.
4. Stack the sheets, assemble the positive and negative electrode sheets and separator together. After bonding is completed, the electrode core is formed.
5. Assemble the soft battery, place the polar core produced in the previous step into the aluminum-plastic film that was pperforated and complete the top sealing, side sealing, etc. -battery pack without liquid injection.
6. Inject the specified amount of electrolyte into the soft battery core.
Lithium batteries are batteries that use lithium metal or lithium alloy as the negative electrode material and use a non-aqueous electrolyte solution. This battery is therefore also called a lithium metal battery. Unlike other batteries, lithium batteries have the characteristics of high charge density, long life and high unit cost.
