Abstract:
An elongate air depolarized electrochemical cell, having a length, a top, and a bottom, said air depolarized electrochemical cell comprising:(a) a cathode, including an air cathode assembly extending along the length of said elongate air depolarized electrochemical cell;(b) an anode, including electroactive anode material in an anode chamber disposed inwardly, in said cell, of said cathode assembly;(c) a grommet juxtaposed adjacent a top portion of said cathode assembly, and closing the top of said elongate air depolarized electrochemical cell said grommet having an outer side wall adjacent an outer side wall of said cell;(d) a separator between said anode and said cathode assembly;(e) electrolyte dispersed in said anode material, said cathode assembly, and said separator; and(f) a liquid barrier seal extending into a slot between said outer side wall of said grommet and an outer side wall of said electrochemical cell, adjacent said grommet,said outer side wall of said electrochemical cell comprising a crimp zone extending about a circumference of said electrochemical cell wherein said outer side wall of said electrochemical cell is crimped inwardly against said liquid barrier seal and through said seal against said outer side wall of said grommet.
