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 and an elongated solid cathode wound in a jellyroll type configuration and shaped in a substantially rectangular cross-section to provided an anode-cathode subassembly which is contained in the casing; c) a separator located between the anode and the cathode to prevent direct contact therebetween; d) a non-aqueous liquid electrolyte in said casing and operatively contacting said anode and said cathode; e) means for electrically connecting one of said anode or cathode to said casing; f) means for electrically connecting the other of said anode or cathode to an electrical connector means extending through said casing in an insulated manner; g) means for hermetically sealing said casing; and h) said elongated anode and said elongated cathode being wound with said elongated anode land said elongated cathode and separator therebetween being in face-to-face contact throughout the entire cross-section of the anode-cathode sub-assembly.
