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 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 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.

摘要： A process for manufacture of manganese dioxide comprising subjecting an aqueous bath comprising manganese sulfate (MnSO4) and sulfuric acid (H2SO4) to electrolysis in a closed cell wherein the electrolysis bath is maintained at an elevated temperature above 110° C., preferably above 115° C. and at superatmospheric pressure. Desirably the bath can be maintained at an elevated temperature between about 115° C. and 155° C. The electrolysis is carried out preferably at elevated current density of between about 12.5 and 37 Amp/sq. ft (135 and 400 Amp/sq. meter) which allows for smaller or fewer electrolysis units. An MnO2 product having a specific surface area (SSA) within desired range of between 18-45 m2/g can be obtained. A doping agent, preferably a soluble titanium dopant is employed to help obtain the desired specific surface area (SSA) of the MnO2 product. The manganese dioxide product in zinc/MnO2 alkaline cells gives excellent service life, particularly in high power application.

摘要： An electrochemical cell containing a decomposing electrolyte solvent, further contains small amounts of an additive material such as lithium sulfide which causes partial self discharge of the cathode of the cell with non-reactive products. The self discharge partially deactivates substantially all of the active cathode surface as a reaction site thereby reducing the decomposition of the electrolyte solvent.
