Abstract:
An air depolarized electrochemical cell, having a top, a bottom, and a length extending between the top and the bottom, said air depolarized electrochemical cell comprising:(a) a cathode, including an air cathode assembly extending along the length of said cell;(b) an anode, including electroactive anode material disposed inwardly, in said cell, of said cathode assembly;(c) a separator between said anode and said cathode assembly;(d) electrolyte dispersed in said anode, said cathode, and said separator;(e) a top closure member closing the top of said cell; and(f) a bottom closure member closing the bottom of said cell, said bottom closure member having an outer side wall, a lowest extremity of said bottom closure member, and an inner side wall extending upwardly from said lowest extremity such that the lowest extremity is disposed between the inner side wall and the outer side wall, the inner and outer side walls, in combination, defining a slot therebetween wherein said inner and outer side walls are opposite each other and oppose each other on opposing sides of the slot, said outer side wall applying a crimping bias directed transverse to the length of said cell and against a surface of said cathode assembly and thereby against the inner side wall, and correspondingly developing a friction fit holding said cathode assembly in the slot between said outer and inner side walls.
