摘要： This invention pertains to novel alkaline electrochemical cells having high drain capacities, especially cells having high drain rate capabilities at voltages of at least 1.1 volts for use in small appliances such as hearing aids. The anode includes anode material in the cells including potassium hydroxide, zinc powder, 0.02% to 0.5% indium as indium compound separate from the zinc powder, optionally a low level of mercury, and preferably a surfactant comprising hydroxyethylcellulose. The cathode provides sufficient oxidative capability to oxidize the zinc at a sufficient rate to support the electrical drain demands on the cell. A cathode, in a preferred zinc air cell for a hearing aid, includes at least 5 air ports, evenly distributed over the surface of the bottom of the cathode can. Cells of the invention exhibit prolonged operation at relatively constant voltage over 1.1 volts, and relatively constant power output at a power density of at least about 210 milliwatts per square inch of the reaction surface area of the cathode assembly, for periods significantly longer than conventional cells.

摘要： An electrochemical cell having a lithium or lithium alloy anode, a solid cathode, and a nonaqueous, liquid electrolyte, includes an amount of a potassium salt which is effective to lower the open circuit voltage of the cell without causing any significant detrimental effects such as corrosion of the anode or self discharge of the cell. More specifically, the electrolyte comprises one or more organic solvents, an electrochemically active amount of one or more primary salts, and more than about 0.001 mol/l of one or more potassium salt additives which achieve the desired open circuit voltage without any harmful effects on the cell. The potassium salt additives have also been found to enhance load voltage on the first 50% depth of discharge, indicating improved rate performance.

摘要： The cathode of the water-activated battery is a chloride member with a silver coating on its surface or it is a silver-chloride cathode. The anode is a magnesium plate. The anode and cathode are spaced apart with a rigid spacer member. A battery casing encloses the electrodes. A conductive liquid such as saltwater enters the housing through entry and exit ports formed therein and the water then surrounds the electrodes. Lead wires, e.g. a wire bundle, project through the casing wall and they connect to a light or a similar load. The battery is operated by immersing the housing into the conductive liquid, removing the entry port plug from the entry port to permit the conductive liquid to enter the casing through the entry port, and removing the exit port plug from the exit port to permit the conductive liquid to exit the casing through the exit port.

The substrate is capable of being connected to electrical circuitry. Most preferably, the substrate is a metal screen that has been hardened, roughened and pitted by sandblasting before the catalytically active materials are disposed thereupon, and before the substrate is incorporated into an electrochemical metal air cell.

摘要： The invention relates to the manufacture of manganese dioxide by a chemical process. The resulting manganese dioxide product takes the form of particles characterized by filament-like protrusions jutting out from its surface. The manganese dioxide particles having such surface features can be manufactured by reacting manganese sulfate with sodium peroxodisulfate in an aqueous solution. The process can be controlled to yield high density manganese dioxide. The manganese dioxide formed in the process can be deposited directly onto the surface of electrolytic manganese dioxide (EMD). The manganese dioxide product is particularly suitable for use as a cathode active material in electrochemical cells.
