  • Patent number: 7886568
    Abstract: In a rolling step of feeding an electrode hoop (1) having electrode mixture layers (3a, 3b) formed on both sides of a band-shaped core (2) made of a metal thin plate to between a pair of mill rolls (8a, 8b) for rolling, the electrode hoop (1) is fed so that side a is wound about one of the mill rolls if the electrode mixture layers (3a, 3b) of the electrode hoop (1) have different average thicknesses, where the side a is one of the electrode mixture layers of the electrode hoop (1) having the smaller average thickness and side b is the other. This realizes a method for rolling an electrode hoop capable of making a rolled flat electrode even if the electrode mixture layers on both sides of the core have respective different thicknesses.

  • Publication number: 20110014508
    Abstract: A nickel metal hydride rechargeable battery has a closed-end tubular container containing a spiral-shaped electrode assembly formed by winding a negative electrode (1) and a positive electrode with a separator interposed therebetween such that the outermost periphery of the assembly is the negative electrode (1), the negative electrode (1) being formed by disposing on a conductive substrate a mixture layer containing a hydrogen-absorption alloy, the positive electrode employing nickel hydroxide as an active material. In the nickel metal hydride rechargeable battery, the surface roughness of the outermost peripheral portion of the mixture layer of the negative electrode (1) which contacts an inner side wall of the closed-end tubular container is 3.5 ?m or more in terms of ten-point average roughness and is larger than the surface roughness of the other portion of the mixture layer. The reduction of oxygen gas during rapid charging is thereby facilitated without lowering the design capacity of the battery.

  • Publication number: 20090202707
    Abstract: A method for applying electrode mixture paste in which a strip of core material (1) made of porous metal sheet is driven to run along its lengthwise direction, is turned around part of the outer surface of a roll (8) immersed in the electrode mixture paste (6), and is driven forward by rotating the roll (8) so that the paste (6) is applied on both sides of the core material (1), after which the coating thickness of the paste (6) is adjusted and the coated paste (6) is dried. The roll (8) is formed with grooves (16) in the outer surface extending along the rotating direction so that the electrode mixture paste (6) that has entered between the outer surface of the roll (8) and the core material (1) is smoothly released, whereby the core material (1) is prevented from meandering and deterioration of coating precision is avoided. The invention thus realizes a method for applying electrode mixture paste that avoids deterioration of coating precision even when the paste has a high viscosity.

  • Publication number: 20090053399
    Abstract: An electrode mixture paste (5) is applied on both sides of a strip of core material (1) as it runs along its lengthwise direction, and the coating thickness of the paste (5) is adjusted as the core material (1) coated with the paste (5) passes through a gap between a pair of scraper tools (16a, 16b). Tips (18) provided to the scraper tools (16a, 16b) scrape off the paste (5) to form a paste-coated portion of a predetermined width. The electrode mixture paste (5) scraped off with the tips (18) is returned through recesses (19) on the upstream side of the tips (18) in the running direction of the core material, so as to prevent the phenomenon where the coating thickness is increased at both side edges of the paste-coated portion. Thus, a method for applying electrode mixture paste is realized that can prevent the phenomenon where the coating thickness is increased at both side edges of the paste-coated portion and prevent process failures such as deformation of paste-coated sheet.

  • Publication number: 20080261105
    Abstract: A nickel hydrogen storage battery is provided which includes an electrode assembly formed by winding spirally a strip-like negative electrode (4) and a strip-like positive electrode with a separator interposed therebetween, the strip-like negative electrode (4) having a mixture layer containing a hydrogen storage alloy disposed on a core material. The electrode assembly is contained in a bottomed cylindrical container such that the negative electrode (4) forms the outermost peripheral portion. A portion corresponding to an outermost peripheral portion (5) of the negative electrode is a thin portion, and the thin portion is bent in advance in the winding direction of the electrode assembly to form an arc shape. In this manner, when the spirally wound electrode assembly is configured, the outermost peripheral portion of the negative electrode is prevented from peeling from the electrode assembly, and thus the insertability into the bottomed cylindrical container is improved.
