Abstract
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.
