Abstract: A solid cathode liquid organic electrolyte alkali metal high rate cell wherein a combination of an elongated alkali metal anode and elongated solid cathode with separator therebetween is wound to form an anode-cathode subassembly having a jellyroll type configuration and wherein the combination is shaped so that the resulting sub-assembly has a substantially rectangular cross-section, the shaping of the combination being done either simultaneously with or subsequent to the winding thereof. The anode-cathode sub-assembly is placed in a conductive cell casing of prismatic shape having opposed flat faces, a lead of either the anode or cathode is attached to the cell casing depending upon whether case positive or case negative electrical configuration is desired and a lead of the other of the anode or cathode is connected to an electrical connector means extending through the casing in an insulated manner. Liquid electrolyte is introduced to the anode-cathode sub-assembly in the casing whereupon the casing then is sealed closed. The foregoing provides a new and improved prismatic high rate battery which significantly reduces the time required to manufacture the cell stack assembly while maintaining the requisite performance, safety and reliability standards in operation,

Abstract: A new process for manufacturing a cathode component from a free-standing sheet of cathode material, is described. The process comprises a first step of adjusting the particle size of the cathode active material to a useful size followed by mixing with binder and conductive additives suspended in a suitable solvent to form a paste. The paste is then fed into a series of roll mills to form the sheet material, or the paste can first be pelletized before the rolling step. The cathode sheet material is dried and punched into cathode plates having a myriad of geometric shapes suitable for cathode preparation by compressing a current collector between two plates of the cathode material.

Abstract: A lithium-iodine cell comprising a pair of cup-shaped container elements each having a peripheral flange and each containing a lithium anode element and iodine-containing cathode material. The container elements are of material which is heat sealable and which does not exhibit electronic conduction when exposed to iodine. The container elements are juxtaposed with the cathode material of each container being in operative contact with a cathode current collector, and the peripheral flanges of the container elements are heat sealed together. The cell is encapsulated in potting material which is non-reactive with iodine, and the encapsulated cell is contained in an hermetically sealed metal casing having rounded surfaces.
