Abstract: A method for preventing thionyl chloride depolarizer cells from exploding by pressure relieving such cells at a low pressure.

Abstract: Fragmentation with electrical discontinuity in a consumable electrode of an electrochemical cell is minimized by preventing a portion of said electrode from reacting by means of a reaction barrier.

Abstract: Abuse resistant electrochemical cells having consumable fluid depolarizer/electrolyte solvents, active metal anodes and inactive conductive cathodes which are made resistant to abusive forced discharge or cell reversal conditions by maintaining excess portions of both the fluid depolarizer/electrolyte solvent with electrolyte and the active metal anode at the end of cell discharge. The remaining portion of the active metal is electrically connected to the negative terminal of the cell and substantially faces the entire surface of the originally adjacent inactive cathode. The remaining portion of the fluid depolarizer/electrolyte solvent is sufficient for maintaining electrical and thermal conductivity whereby heat concentration is prevented.

Abstract: An electrochemical cell containing a polyvalent film forming metal anode, a nucleophilic non-aqueous electrolyte solvent and a free radical forming carbon halide additive dissolved in said solvent.

Abstract: Novel electrolyte salts having high current carrying capability for non-aqueous electrochemical cells particularly those containing fluid depolarizer/electrolyte solvents. The salts have the general formula M(ZX.sub.4).sub.n with "M" being an alkali or alkaline earth metal, "Z" being gallium, indium or thallium, "X" being a halogen and "n" being either 1 or 2.

Abstract: A metal-air battery usually comprises a plurality of air-depolarizable cells within a battery case. The present invention provides that the battery case has a vent and a vent cover, where the vent cover is associated with an electrical actuator so as to open only when the battery is supplying electrical power to a load. In this manner, the metal-air battery is open to the atmosphere only when it is operating, and consequently is open to the possibility of harsh ambient conditions such as very high or very low ambient relative humidity, prolonged carbon dioxide exposure, and so on; and as a consequence, a long operating life for the battery which operates only intermittently during that life can be expected.

Abstract: An electrical device stabilized for long life operation comprising a cathode electrode including a porous layer of electrically conductive metal containing material, an electrolyte including an inorganic acid contacting the cathode electrode, and a cathode depolarizer including copper salt. A method of depolarizing an electrical device comprising the steps of forming a cathode electrode of layers of materials including a porous layer of electrically conductive metal containing material, contacting the cathode electrode with an electrolyte including an inorganic acid and a depolarizer including copper salt, reducing the copper salt to copper, and depositing copper on the cathode electrode as copper metal.

Abstract: A process for treating monovalent silver oxide (Ag.sub.2 O) alone or in combination with other materials to increase its compressibility, increase its ability to absorb electrolyte, and decrease its carbon dioxide absorption rate by the step of heating the silver oxide or silver oxide mixture to temperatures of from about 150.degree. C to about 300.degree. C for a period of time from about 1 hour to about 5 hours.
