摘要： A primary alkaline electrochemical cell containing cathodic materials insoluble in alkaline electrolyte which exhibits increased cell performance at low temperatures, yet does not exacerbate handling and processing problems during cell construction comprises a powdered metallic anode (e.g. zinc) having a aqueous alkaline electrolyte dispersed therein, a cathode (e.g. essentially of manganese dioxide) which is insoluble in said aqueous alkaline electrolyte, and a separator placed therebetween, wherein the separator forms an alkaline resistant non-porous barrier between said anode and said cathode. The separator may comprise two lyers of an absorbent porous separator material and a barrier type membrane placed therebetween, which preferably has a pore size of approximately 2,5 to 4,0 nm and allows for the transfer of electrolytic ions. The absorbent porous separator material absorbs at least 180 % of its weight of said alkaline electrolyte.

摘要： Alkaline electrochemical cells are disclosed 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. Such a cell (10) has an anode (22) with an anode can (24) which contains anode material (26) 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 cell (10) has a cathode (40) which provides sufficient oxidative capability to oxidize the zinc at a sufficient rate to support the electrical drain demands on the cell. The cathode (40), preferred zinc air cell for a hearing aid, has a cathode can (44) which includes at least 5 air ports (54), evenly distributed over the surface of the bottom of the cathode can. Such a cell can 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 prolonged periods.
