Materials and methods for electrode fabrication

Abstract

Provided herein are materials for use and processes of forming a material suitable for use in coating an electrically conductive substrate as used in an electrode for an electrochemical cell. The processes combine a cathode active material, a binder comprising a halogenated hydrocarbon polymer, a solvent, and an additive suitable for reacting with a double unsaturation when formed on the binder, and intermixing the cathode slurry to produce a cathode coating material. The presence of the additive is to react with one or more conjugated dienes formed by reaction of the binder with the cathode active material or portion thereof so as to prevent gelling or unacceptable increases in viscosity during electrode formation or storage of the cathode coating material.
