Abstract:
An electrochemical cell, comprising:(a) a first electrode having spaced apart major faces extending to and meeting with an upper edge and a lower edge joining with a leading edge and an ending edge, wherein at least two leads extend outwardly at spaced intervals from at least one of the upper edge, the lower edge, the leading edge and the ending edge of the first electrode, and wherein the at least two leads are connected to a terminal for the first electrode;(b) a counter electrode operatively associated with the first electrode;(c) a separator disposed between at least one of the spaced apart major faces of the first electrode and the counter electrode, wherein the separator is unsealed at the edge having the leads extending from the first electrode so as not to completely envelope a length of the first electrode adjacent to the leads and the spaced interval between them; and(d) an insulator sheet having a length and a width sufficient to cover the length of the unsealed edge having the leads, wherein the insulator sheet includes at least two slots sized and shaped to snugly receive the at least two leads, and wherein a portion of the insulator sheet overlaps the separator to segregate the first electrode and its leads from the counter electrode.
