摘要： Cathode cans (34) for use in air depolarized cells (10), and cells made with such cans are disclosed; the can side wall (37) is stronger than the bottom wall (36) and has a smoother outwardly-disposed surface than the respective bottom wall surface. Strength, and thus hardness, of the side wall (37) relates to the strength, and thus hardness, of the bottom wall, side wall hardness is 130-185 compared to bottom wall hardness of 93-117, on the Vickers scale. The side wall (37) is drawn, and an outwardly-disposed surface (48) of the side wall is ironed, and its surface finish is related to the surface finish of the bottom wall, at the same stage, as side wall surface finish R A of less than 2, preferably about 0.5 to about 1.5 microinches, is related to bottom wall surface finish R A of about 2 to about 5, preferably about 2.5 to about 4.5 microinches. The side wall has a thickness generally up to about 85 percent as great as thickness of the bottom wall. In the methods of forming cathode cans in a metal strip, use is made of a die (82) which has an initializing land (102), an inner side wall (100), a cavity (101) inwardly of the inner side wall, and a lip (103) between the initializing land and the inner side wall. The ratio of outer radius (104) of the lip (103) to inner radius (106) of the lip is about 2/1 to about 8/1. Ratio of clearance between punch (80) and die (82) to thickness of the metal strip is about 0.5/1 to about .85/1, whereby moving the punch and metal strip into the cavity draws the metal, and irons the outer surface of the metal.

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.
