An ultracapacitor comp rising at least one cell, said cell comprising two solid, nonporous current collectors, two porous electrodes separating said current collectors, a porous separator between said electrodes, an electrolyte occupying pores in said electrodes and separator, said cell sealed with a reclosable hermetic closure.
A stack of ultracapacitor cells, comprising:
- (A) a plurality of bipolar double layer ultracapacitor cells in stacked relationship, at least one of said cells comprising porous, oppositely charged electrodes with an ionically charged separator disposed between said electrodes;
- (B) a non-porous current collector between each cell with each current collector having adjoining polarized electrodes of different cells bonded thereto;
- (C) an electrolyte saturating said charged electrodes and separators;
- and
- (D) a reclosable hermetic closure sealing at least one cell of said stack.
