RECHARGEABLE BATTERY AND METHOD FOR MANUFACTURING POSITIVE PLATE OF RECHARGEABLE BATTERY
DRIVE
June 8, 2023
A method for manufacturing a positive plate of a rechargeable battery includes producing an insulation protective paste forming an insulation protective layer of the positive plate, the insulation protective paste including insulation particles, a binder, and a solvent and having a pH adjusted corresponding to a zeta potential at which the insulation particles do not aggregate, producing a positive composite material paste forming a positive composite material layer of the positive plate, the positive composite material paste including a positive active material, a conduction support, a binder, and a solvent, and a pH adjuster being added to the positive composite material paste to adjust a pH corresponding to a zeta potential at which the insulation particles aggregate, and simultaneously coating a positive current collector of the positive plate with the positive composite material paste and the insulation protective paste disposed adjacent to an end of the positive composite material paste.
