Abstract
An electric energy storing device constructed from uniquely designed components. Each component includes a first nonconductive frame, having an opening and a predetermined perimeter. Mounted, by its peripheral edge, on the first nonconductive frame, is a plastic sheet, having a centrally positioned opening. The plastic sheet may be made from conductive carbon plastic or from nonconductive, ion-permeable plastic. Mounted to the centrally positioned opening of the plastic sheet is a second nonconductive frame. Each of the frames has a weld bead thereon and a plurality of components are welded together to form an operational device. The provision of a second, centrally located weld prevents deformation or defection at the center of the welded components.
