ELECTROCHEMICAL CELL Abstract of the Disclosure A primary electrochemical cell of a design for reducing or minimizing parasitic self-discharge of the cell during storage and subsequent discharge of the cell. The cell includes a tubular porous carbon cathode struc- ture disposed within a metal housing of the cell and spaced from an anode structure by an insulative separator material. The carbon cathode structure and the anode structure are exposed to an electrolytic solution includ- ing a reducible soluble cathode (e.g., thionyl chloride) which is catalytically reduced during discharge of the cell at the surface of the carbon cathode structure. The anode structure includes an elongated, cylin- drical lithium electrode located centrally within, and spaced from, the housing, and a thin, bare, flexible metal element at the potential of the lithium electrode and coupled between the lithium electrode and a feed- through member provided in a top cover of the housing. The surface areas of the flexible metal element and the lithium electrode are established such that the surface area of the wire is about 1-10 percent of the initial (pre-discharge) surface area of the lithium electrode for minimizing the parasitic catalytic reduction of the soluble cathode at the surface of the flexible metal element. The flexible metal element and feedthrough member may also be covered with an anti-parasitic discharge material for preventing catalytic reduction of the soluble cathode at the surfaces of the flexible metal element and feedthrough member covered with the anti- parasitic discharge material.
