Batching
Batching: According to the material system, dry powder and binder are mixed with certain stirring parameters and time. After the slurry is prepared, check the viscosity and solid content of the slurry
Coating
Coating: The negative electrode substrate is copper foil, and the positive electrode substrate is aluminum foil. The well-stirred slurry is coated on the foil as positive and negative electrodes, and then the diluent is evaporated and dried in an oven.
Roll pressing
Roll pressing: According to the process requirements, the coated coil is pressed in a certain compaction ratio to smooth the floating powder on the surface.
Slitting
Slitting: According to the length requirements of different models and certain specifications, the rolled materials after roll pressing are divided into small rolls.
Sheet Making
Sheet Making: Weld tabs on the positive and negative electrode sheets, and apply adhesive tape for insulation at the welded tab positions.
