Abstract
A cathode coating dispersion containing graphite and/or carbon black, which is suitable for battery production, especially for a water-resistant and alkali-resistant and yet electrically conductive coating of the cathode surfaces. The protective film is applied as a homogeneous aqueous dispersion and contains a binder which is a copolymer of (a) vinyl acetate and ethylene, (b) vinyl acetate and vinyl chloride, (c) styrene and butadiene or (d) vinyl acetate, vinyl chloride and ethylene.
