  • Patent number: 8475876
    Abstract: An electrode mixture paste is applied on both sides of a strip of core material as it runs along its lengthwise direction, and the coating thickness of the paste is adjusted as the core material coated with the paste passes through a gap between a pair of scraper tools. Tips provided to the scraper tools scrape off the paste to form a paste-coated portion of a predetermined width. The electrode mixture paste scraped off with the tips is returned through recesses on the upstream side of the tips 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.

  • Patent number: 8475958
    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.

  • Publication number: 20130136895
    Abstract: A thermally conductive sheet has cut surfaces with low surface roughness and hence shows reduced thermal resistance at the interfaces, and high thermal conductivity in the thickness direction. Thus, the thermally conductive sheet can be interposed between any of various heat sources and a radiation member. The process for producing the thermally conductive sheet includes at least: an extrusion molding step in which a thermally conductive composition containing a polymer, an anisotropic thermally conductive filler, and a filler is extruded with an extruder to thereby mold an extrusion-molded product in which the anisotropic thermally conductive filler has been oriented along the extrusion direction; a curing step in which the extrusion-molded product is cured to obtain a cured object; and a slicing step in which the cured object is sliced into a given thickness with an ultrasonic cutter in the direction perpendicular to the extrusion direction.

  • Patent number: 8389159
    Abstract: A nickel metal hydride rechargeable battery has a closed-end tubular container containing a spiral-shaped electrode assembly formed by winding a negative a positive electrode with a separator interposed therebetween such that the outermost periphery of the assembly is the negative electrode which is formed by disposing on a conductive substrate a mixture layer containing a hydrogen-absorption alloy. The positive electrode employs 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 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.
