1. A nonaqueous electrical storage device comprising:

  • first and second high surface area electrodes in contact with a nonaqueous electrolyte;

    a conductive polymer current collector in contact with each of said electrodes, said polymer current collector having a flow temperature greater than 130°

    C.;

    a separator, between and in contact with each of said electrodes, said separator maintaining a physical spacing in said electrolyte while allowing ionic conduction between each of said electrodes; and

    a gasket sealing said storage device, said gasket comprising a thermoplastic material that is stable above 100°

    C., said thermoplastic material also having a reflow temperature above 130°

    C. but below a softening temperature of said conductive polymer current collector.
