A method for making a molded plastic component for a bipolar battery, such as a lead-acid battery, comprises molding a plastic frame about a thin electrically conductive substrate, embedding the periphery of the substrate in the plastic frame and then removing the warpage resulting from the molding by a suitable surface reformation step, as by die stamping, to restore a surface that will allow desirable electrical performance to be achieved when the bipolar battery is used in service.

A method for making a modular molded plastic component for a bipolar battery, said component comprising an electrically conductive substrate having its periphery embedded in a molded plastic frame and the remainder of the surface exposed to accept an active material paste which method comprises providing a molded plastic component wherein the substrate has warpage and thereafter subjecting the substrate surface available to accept an active material paste to surface reformation in a configuration to eliminate the warpage in other than the area of the surface reformation.
