摘要： A process for heat treating an anode casing of a zinc/air depolarized cell after the casing has been formed but before anode material comprising zinc is inserted therein. The anode casing has a layer of copper on its inside surface. The process comprises heat treating the anode casing by passing a gas at a temperature between about 200° C. and 700° C., preferably between about 300° C. and 600° C. in contact therewith to form a heat treated anode casing and then cooling said heat treated anode casing to ambient temperature. The heat treated anode casing is stored away from atmospheric air until anode active material is inserted therein during cell assembly. The heat treating process significantly reduces gassing during cell discharge and storage and eliminates the need to add mercury to the anode material.

摘要： This invention relates to an electrochemical cell having spirally wound electrodes and an electrolyte which enhances plating of the anode metal during voltage reversal. The safety of such cells is improved by concentrating the current, during voltage reversal, between an outer segment of the anode and a metal sheet connected to the cathode whereby anode metal plates only onto the metal sheet. Thus, the hazardous condition of plating anode metal onto the cathode is avoided.

摘要： A nonaqueous electrochemical cell and a method for the construction thereof wherein the cell contains a metal salt additive such as lithium nitrate (LiNO.sub.3) or calcium nitrate Ca(NO.sub.3).sub.2 which reduces the reactivity of substantially the entire active cathode surface. Electrolyte solvents such as propylene carbonate are thereby substantially prevented from reacting, on the surface of the cathode, with oxidizing agents within the cell. Decomposition of the electrolyte solvent with gaseous evolution is substantially reduced and cell stability is enhanced. The metal salt additives are particularly useful in nonaqueous cells containing manganese dioxide cathodes.

摘要： This invention provides a design for spirally wound electrochemical cells which improves their safety during abuse such as voltage reversal. The invention comprises coupling a first segment of inert conductive metal to the cathode and a dendrite target comprised of an inert conductive metal to the anode. When these electrodes are spirally wound together the two segments of inert conductive metal face each other, held in physical separation by the separator, whereby during voltage reversal a dendrite grows from said first segment to said dendrite target.

摘要： The safety of a non-pressurized electrochemical cell such as a Li/MnO.sub.2 cell, having a safety pressure vent and an organic electrolyte solvent is enhanced by, in conjunction with said vent, providing said organic electrolyte solvent with at least 80% by volume of a volatile component, such as dimethoxyethane, having a boiling point between 30.degree. C. to 130.degree. C. Upon cell venting, under abuse conditions, the cell is thereby rapidly evacuated and safely rendered inoperable under further abuse conditions.
