摘要: A lithiated manganese dioxide for use in primary lithium electrochemical cells. The lithiated manganese dioxide is prepared by stepwise treatment with a liquid source of lithium cations that can include an aqueous solution of a lithium base or a low melting point lithium salt resulting in formation of a lithiated manganese dioxide product. Lithium cations in the lithium base or molten lithium salt can be ion-exchanged with hydrogen ions in the manganese dioxide crystal lattice and additional lithium ions reductively inserted into the lattice during subsequent heat-treatment to form the lithiated manganese dioxide product LiyMnO2−&dgr;. The primary lithium cell utilizing the lithiated manganese dioxide product as active cathode material exhibits increased operating voltage and enhanced high rate, low temperature, and pulse discharge performance compared with untreated manganese dioxide.

摘要: A process for heat treating the metal sheeting forming the anode casing of a zinc/air depolarized cell before anode material comprising zinc is inserted into the anode casing. The anode casing has a layer of copper on its inside surface. The process comprises heat treating the metal sheeting forming 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 sheeting and then cooling said heat treated sheeting to ambient temperature. The 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. The cell's capacity and performance is improved when the cell's anode comprises particulate zinc (or zinc alloy) plated with indium, preferably between about 200 and 600 ppm indium. The need to add mercury to the anode material is reduced and can be eliminated.

摘要: A non-aqueous electrolyte cell particularly one containing a beta manganese dioxide cathode wherein the cathode is normally rigorously heat treated to drive off contained water. The heat treatment is substantially reduced or eliminated (allowing up to 2% water by weight of the cathode to remain in the cell) by utilizing as an electrolyte salt in the cell, a salt which reacts with water to only form a weak oxidizing agent which in turn does not react with the electrolyte solvent to form a gaseous product. Alternatively, an electrolyte solvent is initially utilized in the cell, which solvent does not react with strong oxidizing agents to form a gaseous product.

摘要: A fluorosurfactant, preferably an anionic fluorosurfactant, can be added to the anode mixture of a zinc/air cell. A desirable surfactant is an anionic fluoroaliphaticcarboxylate. The addition of the surfactant reduces gassing and improves cell performance. The anode casing can also be treated with the surfactant solution prior to inserting the anode mixture therein. The anode casing of a zinc/air depolarized cell can also be heat treated 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.
