CATHODE COATING DISPERSION FOR BATTERIES

摘要

A cathode coating dispersion containing graphite and/or carbon black is disclosed which is suitable for battery production, especially for forming a waterresistant and alkali-resistant and yet electrically conductive coating on 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, or (b) vinyl acetate and vinyl chloride, or (c) styrene and butadiene or (d) vinyl acetate, vinyl chloride and ethylene.
