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.

Claims

1. A component for an electric energy storing device, the component comprising:

a first nonconductive frame having an opening and a perimeter;

a plastic sheet having a peripheral edge and an opening, the peripheral edge of the plastic sheet mounted on the first frame; and

a second nonconductive frame having an opening and a perimeter which is less than the perimeter of the first frame and mounted on the opening of the plastic sheet.

2. A component for an electric energy storing device as claimed in claim 1, and wherein the second nonconductive frame is positioned in coaxial relationship to the first frame.

3. A component for an electric energy storing device as claimed in claim 1, and wherein the first nonconductive frame further includes a first peripheral edge having an electrolyte orifice and an electrolyte flow channel, and a second peripheral edge having an electrolyte orifice and an electrolyte flow channel.

4. A component for an electric energy storing device as claimed in claim 3, and wherein the first nonconductive frame further includes a reservoir opening coupled to the electrolyte orifice of the first peripheral edge and having an electrolyte outlet.

5. A component for an electric energy storing device as claimed in claim 4, and wherein the first nonconductive frame further includes a second reservoir opening positioned in the first peripheral edge of the first nonconductive frame and having an electrolyte outlet.

6. A component for an electric energy storing device as claimed in claim 1, and wherein the plastic sheet is a sheet of conductive, carbon plastic.

7. A component for an electric energy storing device as claimed in claim 1, and wherein the plastic sheet is a sheet of nonconductive, ion-permeable plastic.

8. An electric energy storing device comprising:

a plurality of first nonconductive frames, each having an opening and a perimeter;

a plurality of conductive, carbon-plastic sheets, each having a peripheral edge and a centrally positioned opening, the peripheral edge of each conductive, carbon-plastic sheet mounted on a first number of the plurality of first nonconductive frames;

a plurality of nonconductive, ion-permeable plastic sheets, each having a peripheral edge and a centrally positioned opening, the peripheral edge of each nonconductive, ion-permeable plastic sheet mounted on a second number of the plurality of first nonconductive frames;

a plurality of second nonconductive frames, each having an opening and a perimeter which is less than the perimeter of each of the first nonconductive frames, a first number of the second nonconductive frames mounted on the centrally positioned opening of the conductive, carbon-plastic sheets, and a second number of the second nonconductive frames mounted on the centrally positioned opening of the nonconductive, ion-permeable plastic sheets;

wherein the individual frame-mounted, nonconductive, ion-permeable sheets are arranged in alternating, sandwich relation to the individual frame-mounted, carbon-plastic sheets.

9. A component for an electric energy storing device, the component comprising:

a first nonconductive frame having an opening, a perimeter, and at least one electrolyte flow channel;

a plastic sheet having a peripheral edge and an opening, the peripheral edge of the plastic sheet mounted on the first frame; and

a second nonconductive frame having an opening and a perimeter which is less than the perimeter of the first frame and mounted on the opening of the plastic sheet.

10. A component for an electric energy storing device as claimed in claim 9, and wherein the plastic sheet is a sheet of conductive, carbon plastic.

11. A component for an electric energy storing device as claimed in claim 9, and wherein the plastic sheet is a sheet of nonconductive, ion-permeable plastic.
