Abstract:
A solid cathode liquid electrolyte alkali metal high rate cell for delivering successive high current pulses and rapidly recovering the cell open circuit voltage and comprising:a) a casing of electrically conductive material and of prismatic shape having opposed flat faces;b) an elongated alkali metal anode having an edge extending along a length thereof and an elongated solid cathode having an edge extending along a length thereof, said anode and said cathode being wound in a jellyroll configuration wherein said anode and said cathode are in operative contact beginning at the center of the jellyroll configuration and throughout the entire cross-section of the jellyroll configuration and shaped in a substantially rectangular cross-section to provide an anode-cathode subassembly which is contained in said casing;c) a non-aqueous liquid electrolyte in said casing and operatively contacting said anode and said cathode;d) first tab means extending from the edge of one of said anode or cathode for electrically connecting one of said anode or cathode to said casing;e) second tab means extending from the edge of the other of said anode or cathode for electrically connecting the other of said anode or cathode to an electrical connector means extending through said casing in an insulated manner;f) said first and second tab means being in spaced relation alone a dimension of the anode-cathode subassembly; andg) means for hermetically sealing said casing;h) so that relatively few leads are required for making electrical connection to said anode-cathode subassembly thereby resulting in a significant simplification and reduction in time for manufacture of the cell.
