Abstract: An energy compression device includes at least one bipolar element comprising a positive electrode formed of cobalt disulfide, a negative electrode formed of a lithium alloy, an inert porous separator disposed between and in contact with the electrodes, and a lithium cation salt dispersed through the separator and in contact with, and preferably dispersed through, the electrodes.

Abstract: The present invention relates to a titanium wire reinforced lead composite electrode support structure for use in lead-acid batteries comprising a titanium wire reinforced cast lead composite having titanium wires embedded in a cast lead matrix. The composite support structure may be made in the form of a lead grid for use in Faure type batteries, as a support structure for tubular type batteries, or as plates for use in Plante type batteries.

Abstract: The corrosion rate of low carbon steel within a positive electrode of a high-temperature, secondary electrochemical cell that includes FeS as active material is substantially reduced by incorporating therein finely divided iron powder in stoichiometric excess to the amount required to form FeS in the fully charged electrode. The cell typically includes an alkali metal or alkaline earth metal as negative electrode active material and a molten metal halide salt as electrolyte. The excess iron permits use of inexpensive carbon steel alloys that are substantially free of the costly corrosion resistant elements chromium, nickel and molybdenum while avoiding shorten cell life resulting from high corrosion rates.
