1. A device, comprising:
an electrode stack including a plurality of conductive anodes, a plurality of conductive cathodes, a plurality of separators arranged between the conductive anodes and the conductive cathodes, and a dielectric material disposed on a surface of each of the conductive anodes, the stack having a top surface, a bottom surface, and an edge extending between the top surface and the bottom surface;
a continuous electrically insulating film overlying the edge, peripheral portions of the top surface and peripheral portions of the bottom surface, wherein a central portion of the top surface and a central portion of the bottom surface are exposed,
the film being a single component and including a continuous central region overlying the edge and peripheral regions on opposite sides of the central region and overlying the peripheral portions of the top surface and peripheral portions of the bottom surface,
the film having a thickness that extends from a first side of the film to a second side of the film without extending beyond the first side and without extending beyond the second side, the thickness of the film in the central region being greater than the thickness of the film in the peripheral regions,
wherein:
the peripheral regions include pleated regions at corners of the top surface and the bottom surface, the pleated regions being formed by portions of the peripheral regions folded over each other, or
the peripheral regions include joints at corners of the top surface and the bottom surface, the joints being formed by abutting edges of the peripheral regions; and
an electrolyte disposed between the conductive anodes and the conductive cathodes.
