Abstract
A method of preparing an electrochemical cell wherein the composite electrode material adheres to the metal current collector to create good electrical contact is provided. The electrode/current collector comprises a current collector, a layer of an electrically conductive adhesion promoter formed on at least one surface of the current collector which comprises an electrically conductive material and an adhesive polymer; and a composite electrode selected from the group consisting of composite cathode and composite anode, wherein the thickness of said electrically conductive adhesive promoter is sufficient to bind the composite electrode to said current collector.
