Abstract
A method of preparing an electrochemical cell wherein the composite electrode material adheres to the current collector to create good electrical contact is provided. The electrode/current collector comprises a current collector having a layer of electrically conductive metal oxide on at least one surface of the current collector and a composite electrode selected from the group consisting of composite cathode and composite anode wherein the layer of metal oxide is positioned between the current collector and composite electrode. The composite electrode remains substantially and permanently attached to the electrically conductive metal oxide layer that has been formed on the surface(s) of the current collector during the life of the electrochemical cell or battery.
