Abstract:
A microcell assembly, wherein each microcell comprises:an inner electrode, a microporous membrane separator in contact with the inner electrode, an electrolyte in pores of the microporous membrane separator, an outer electrode, said assembly comprising a first cell including a first microcell sheet member comprising a plurality of microcell fibers parallelly arranged and interconnected in a substantially planar conformation, with inner current collectors of said microcell fibers axially extending from a first edge of the first cell, and a second sheet member of external current collectors overlying the first microcell sheet member, with each external current collector in contact with at least one microcell fiber of the first microcell sheet member and extending beyond a second, opposite edge of the first cell; an insulating sheet for electrical isolation of the first cell from a further cell overlying the insulating sheet; a second cell including a third microcell sheet member comprising a plurality of microcell fibers parallelly arranged and interconnected in a substantially planar conformation, with inner current collectors of said microcell fibers axially extending from one edge of the second cell that is adjacent to the second, opposite edge of the first cell, and a fourth sheet member of external current collectors overlying the third microcell sheet member, with each external current collector in contact with at least one microcell fiber of the third microcell sheet member and extending beyond the other,,opposite edge of the second cell that is adjacent to the first edge of the first cell; so that the inner current collectors of the first cell are aligned with and electrically connected to the external current collectors of the second cell to form a series connection therewith.
