CATHODE COATING DISPERSION

摘要

PROBLEM TO BE SOLVED: To provide a graphite and/or carbon black-containing cathode coating dispersion which is suitable for battery production. SOLUTION: The dispersion is, water and alkali resistant and also electrically conductive when coated on cathode surfaces, and a one pot thermoset water based system which contains at least two binders selected from epoxy ester and styrene-acrylic, styrene butadiene or butadiene acrylonitrile. The formulation containing butadiene acrylonitrile is also suitable as acid-resistant coating. The dispersion also contains at least one crosslinker such as melamine and/or carbodiimide. The crosslinking is accelerated by using acid catalyst in the dispersion.
