D-22969 ELECTROCHEMICAL CELL ABSTRACT OF THE DISCLOSURE A high-rate, low-temperature, primary electrochem- ical cell. The cell in accordance with the invention includes an elongated cylindrical metal housing within which a vertical array of battery stack components is disposed and exposed to a cathodelectrolyte solution. Each of the battery stack components has an opening therein through which an elongated metal rod located centrally within the housing passes and serves as an electrical terminal for the cell. The components of the battery stack include a plurality of thin, flat, circular,lithium anode discs secured to the metal rod, and a plurality of carbon current collector cathode/insulator structures arranged in the array in alternation with the lithium anode discs. Each of the carbon current collector cathode/ insulator structures includes a generally circular, thin metal current collector spaced from the metal rod by way of the opening therein and having a size and shape so as to generally conform to the interior configuration of the housing and make direct physical contact with an interior wall of the housing. First and second circular, flat, thin, porous carbon layers are disposed on opposite sides of the metal current collector and spaced from the metal rod by way of the openings therein. First and second circular, flat, porous fiberglass insulators integrated with the first and second porous carbon layers, respectively, are in direct physical contact with adjacent ones of the lithium anode discs and separate the porous carbon layers from the adjacent lithium anode discs.
