METHODS FOR MAKING CURRENT COLLECTOR AND ELECTRODE OF ELECTROCHEMICAL BATTERY

摘要

A method for making a current collector of an electrochemical battery is disclosed. In the method, a current collecting metal substrate and a solid graphite source are provided. A graphite/graphene layer is formed on at least one surface of the current collecting metal substrate, by rubbing the at least one surface of the current collecting metal substrate with the solid graphite source. A method for making an electrode of an electrochemical battery is also disclosed.
