Abstract
A method for manufacturing an electrode for a lithium-based battery by electrophoretic deposition is provided. The method includes: mixing particles with graphene oxide and a binder in a solution, the particles including a material selected from silicon, silicon oxide, silicon alloys, tin, tin oxide, sulfur, lithium manganese oxide, lithium cobalt oxide, lithium nickel oxide, lithium nickel manganese oxide, and lithium nickel manganese cobalt oxide. The method further includes applying a potential between a current collector and a counter electrode immersed in the solution to deposit a coating of a combination of the particles, at least partially reduced graphene oxide, and binder onto the current collector. The method still further includes drying the coated current collector.
