摘要： An electrode mixture paste (5) is applied on both sides of a strip of core material (1) made of porous metal sheet that is running along its lengthwise direction. The paste-coated core material (1) is pressed with press rollers (15a, 15b) alternately from opposite sides once or more, after which the paste-coated core material (1) is passed through the gap between a pair of scraper tools (16a, 16b) to adjust the coating thickness of the paste (5), while the position of the core material (1) is restricted with comb-shaped projections (17a or 17a, 17b), so that, even though the projections (17a, 17b) are distanced from each other sufficiently to allow weld points of the core material (1) to pass through, the coating thickness is precisely regulated. Therefore, a method of applying an electrode mixture paste is realized, with which coating thickness is precisely adjusted and, even in a continuous production process in which core materials are connected together by welding, production failures due to weld points being stuck are prevented.

摘要： A battery used by rolling a pole plate, formed by filling an active material, around a substrate using a band-shaped metal porous body having three-dimensionally linked spaces is inferior in flexibility and likely to short-circuit. According to this invention, grooves are formed in an active material-filled substrate filled with the above active material, and then the grooved substrate is pressed flat to form groove active material layers, whereby cracks are made in the bottoms of the grooves preferentially, and cracks are pressed by the groove active material layers and blocked to prevent the flow-out of swelled projections of the cracks and the active material. Accordingly, a higher-capacity and higher-reliability battery is provided.

摘要： A method for manufacturing a positive electrode for an alkaline storage battery that achieves excellent filling characteristics for an active material for the positive electrode and longer lifetime of the battery is provided. The method includes a first process of filling a paste of the active material for the positive electrode in a first porous metal sheet 30 provided with a plurality of oblate pores 30a whose major axes are arranged substantially in one direction, and a second process of pressing the first porous metal sheet 30 that has undergone the first process using a roller press such that the one direction and a direction of a rotation axis 31a of a roller 31 in the roller press substantially are parallel, so as to produce a positive electrode sheet 40 provided with a second porous metal sheet. In the second porous metal sheet, a value obtained by dividing a length of the pores in the one direction by that of the pores in a direction perpendicular to the one direction and parallel to a surface of the second porous metal sheet averages in the range of 0.9 to 1.1.

摘要： The present invention discloses a method for manufacturing an electrode for a battery by filling an active material into a three-dimensional porous metal substrate sheet and cutting said sheet to a certain size, comprising the steps of: pressing the portion to be cut and the periphery thereof in the substrate sheet; coating the portion to be cut and the periphery thereof in the substrate sheet with a resin; and/or impregnating the portion to be cut and the periphery thereof in the substrate sheet with a liquid containing a resin component, in addition to the steps of: filling an active material into the substrate sheet; and cutting the substrate sheet at the portion to be cut. This method prevents the occurrence of burrs and cuttings while the sheet is being cut and the coming off of the active material, thereby suppressing internal short circuit of the battery. As a result, a battery hardly suffering from a deterioration in preservation performance and charge-discharge cycle life can be obtained.

摘要： Provided is a highly reliable nickel-zinc battery including a separator exhibiting hydroxide ion conductivity and water impermeability. The nickel-zinc battery of the present invention includes a separator exhibiting hydroxide ion conductivity and water impermeability. The separator is disposed in a hermetic container so as to separate a positive-electrode chamber accommodating a positive electrode and a positive-electrode electrolytic solution from a negative-electrode chamber accommodating a negative electrode and a negative-electrode electrolytic solution. The positive-electrode chamber has an extra positive-electrode space having a volume that meets at least part of a variation in amount of water in association with reaction at the positive electrode during charge and discharge of the battery, and the negative-electrode chamber has an extra negative-electrode space having a volume that meets at least part of a variation in amount of water in association with reaction at the negative electrode during charge and discharge of the battery. The battery further includes a gas-liquid flow channel that connects the extra positive-electrode space to the extra negative-electrode space, and the gas-liquid flow channel allows the electrolytic solution and gas in the positive-electrode and negative-electrode chambers to pass through the flow channel in response to a variation in amount of water caused by charge and discharge reactions.
