摘要： This invention pertains to metal-air electrochemical cells wherein one or more air entry ports is located in the bottom of the cathode can, to provide for entry of oxygen-rich air into the cathode can, where the oxygen partcicpates in the chemical reaction whereby the cell produces electrical energy. In this invention, multiple small air entry ports are provided. Generally, the use of multiple ports distributed over the bottom of the cathode can, opposite the reaction surface of the cathode assembly, while not increasing the overall open area of the ports, results in an increase in the ratio of the cell limiting current to the rate at which moisture is lost from the cell. Accordingly, moisture loss as a function of electrical energy produced, is less.

摘要： This invention pertains to novel electrochemical metal air cells having improved closed circuit voltage characteristics. The improved voltage characteristics are illustrated at a constant load of 51 ohms. The closed circuit voltage during an initial placement into use of the cell of the invention has a decreased voltage drop relative to prior art cells, and recovers to a higher voltage. For example, the closed circuit voltage of the metal air cell drops to a minimum voltage during the first 20 seconds of initial placement into use. The minimum voltage is no more than 22% less than the initial open circuit voltage. This voltage drop is less than the voltage drop of other known metal air cells at 51 ohms. Metal air cells of the invention recover, during the first minute of use, to a closed circuit voltage of at least 79% of the initial open circuit voltage. The value of the open circuit voltage of the metal air cell of the invention is preferably about 1.43 volt.

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 elongate air depolarized electrochemical cell (10). A grommet (18) closes the top of the cell (10). A seal (36) can extend upwardly into a slot (174) between the grommet (18) and a top closure member (177) such as at the top of a cathode can (28), or a separate top closure member (200). Cathode assembly (26) and separator (16) can extend into the slot (174). The seal is between the grommet (18) and cathode assembly (26), or between grommet (18) and separator (16). or both. The seal can extend upwardly into the slot (174) from an outer surface of the cathode assembly (26), can extend about respective upper edges of the cathode current collector (57), catalyst, and separator (16), and downwardly toward, preferably against or along the inner surface of, the separator (16). The top closure member (200) can be crimped against the grommet (18) at the slot (174), with the cathode assembly (26), and optionally the separator (16), in the slot (174) between the grommet (18) and the top closure (200), thus to provide a liquid-tight crimp seal. The top closure (200) can be crimped first against the grommet (18) at the slot (174), and further crimped against the grommet (18) at a second locus (178) displaced longitudinally from the first crimp. Composition of the seal comprises a microporous polymer (36), preferably polytetrafluoroethylene. Preferred embodiments comprise at least two, preferably at least three, layers of air permeable microporous sheet material, useful for diffusion of air therethrough to the cathode reaction surface (63). The layers are wrapped continuously and without intervening end, to form an outer surface of the cathode assembly (26). Another expression of the invention is a cathode assembly (26), or cathode-separator combination, for use in an elongate air depolarized cell (10). The air permeable sheet material (36), as wrapped about the tubular cathode assembly, is compressed so as to have a compressed thickness less than the uncompressed thickness. The invention still further comprehends an elongate air depolarized cell (10) comprising an anode, a cathode, or cathode-separator combination as described herein, and electrolyte.

摘要： Cathode cans for use in air depolarized cells, and cells made with such cans. The side wall is stronger than the bottom wall, and has a smoother outwardly-disposed surface than the respective bottom wall surface. Strength, and thus hardness, of the side wall relates to strength, and thus hardness, of the bottom wall, as hardness of 130-185 relates to hardness of 93-117, on the Vickers scale. Preferred hardness of the side wall is about 130 to 185; and of the bottom wall is about 93 to 117. The side wall is drawn, and an outwardly-disposed surface of the side wall is ironed. As ironed, the surface finish is related to surface finish of the bottom wall, at the same stage, as surface finish RA of less than 2, preferably about 0.5 to about 1.5, microinches, is related to surface finish RA of about 2 to about 5, preferably about 2.5 to about 4.5, microinches. Thickness of the side wall is generally up to about 85 percent as great as thickness of the bottom wall. In methods of forming cathode cans in a metal strip, a die has an initializing land, an inner side wall, a cavity inwardly of the inner side wall, and a lip between the initializing land and the inner side wall. Ratio of outer radius of the lip to inner radius of the lip is about 2/1 to about 8/1. Ratio of clearance between punch and die to thickness of the metal strip is about 0.5/1 to about 0.85/1, whereby moving the punch and metal strip into the cavity draws the metal, and irons the outer surface of the metal.

摘要： An elongate, generally tubular, air depolarized electrochemical cell (10) comprising a cathode (14), including an air cathode assembly (26), extending about the tubular circumference, and along the tubular length, of the cell (10), an anode (12), a separator (16) between the anode (12) and the cathode (14), electrolyte, a top closure member (177, 200), and a bottom closure member (114, 202). The cathode assembly (26) is fixedly held, by a friction fit, in a slot (116) at the bottom of the cell. The slot can be developed, for example, by inner (110) and outer (114) wars of a cathode can (28), by inner (226) and outer (224) walls of a bottom closure member (202), or by an outer wall (114) of a cathode can (28) and an opposing outer wall of a plug (128) on the interior of the cell. Preferably, bottom closure structure of the cell (10) and receives a bottom edge portion (44) of the cathode current collector (32), and makes electrical contact with, the bottom edge portion (44), preferably at an inner surface (60) of the cathode current collector. A diffusion member (36) of the cathode assembly (26) is preferably compressed as a seal, at the bottom of the cell (10), between an outer side wall (39) of the cell and the remainder of the cathode assembly (26). The diffusion member (36) is also used at least as an assist in sealing the cell (10) against electrolyte leakage from the anode cavity (137) and past the cathode assembly (26). Various embodiments comprehend a variety of bottom seal members (140, 142) between the bottom wall (37) and the electroactive anode material (20), typically in combination with a bottom slot (116) receiving the cathode assembly (26) adjacent an outer side wall (39) of the bottom closure member (30, 202).
