Li-ion battery major production procedure

1. Mixing: Use a special solvent and a binder to mix with the positive and negative electrode active materials in a powder form respectively. After stirring, the positive and negative electrode materials are prepared into a slurry.

2. Coating: The positive and negative electrode pastes are uniformly coated on the surface of the metal foil by an automatic coating machine, and are automatically cut to form positive and negative electrode pieces after being automatically dried.

3. Assembly: According to the sequence of the positive electrode sheet-separator-negative electrode sheet-membrane from the top to the bottom, the process of injecting the electrolyte, sealing, and positive and negative electrode ear welding is performed by winding, and the assembly process of the Battery is completed and finished product.
