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： In an integrated sealed secondary battery 1 in which a plurality of cells 2 are arranged in a row, cooling medium passages 21 are formed on both sides of the row of the cells 2, and cooling medium passages 18 are formed between adjacent cells such as to effect communication between the cooling medium passages 21, 21 on both sides. The cross-sectional areas of the cooling medium passages 21, 21 on both sides are made different so as to generate pressure difference at both ends of the cooling medium passages 18 between the cases. The cooling medium passages 21 on both sides are formed in a meandering manner by the provision of projection strips that extend alternately downwards from the top wall and upwards from the bottom wall of the cooling medium passages 21.

摘要： A plurality of cells (1a to 1j) are abutted against each other and electrically connected on the short sides of rectangular battery housings (2), and binding plates (14, 14) disposed on both long sides are tied together with binding bands (13) to integrally link the cells (1a to 1j). Because the heat radiation conditions are equalized among the cells (1a to 1j), there is an extremely small temperature differential between the cells, charging efficiency, which varies with temperature conditions, is consistent, and there is no variance in battery capacity, so none of the cells are over-discharged, and battery life is extended.

摘要： A workpiece, in which a lead is laid on top of a three-dimensional porous metal body, is placed between an ultrasonic horn and an anvil with a lead portion facing the ultrasonic horn. A support is raised so that the lead portion of the workpiece is pressed between the ultrasonic horn and the anvil. While being rotated around a central shaft with a motor, the ultrasonic horn vibrates at a frequency of 20 kHz in the shaft direction. Thus, the workpiece is advanced continuously, so that the lead is bonded ultrasonically to the three-dimensional porous metal body (i.e., metal-to-metal bonding is established). It is possible to provide a battery electrode that can be produced continuously at a lower running cost, reduce the faulty welding with a current collecting plate, and prevent short-circuits.

摘要： A sheet separator is so arranged as to cover both surfaces of an electrode plate, and a heating plate is applied along a to-be-bonded edge of the separator, thereby achieving bonding by thermal welding. The heating plate has a width corresponding to a width of a bonded portion of the separator. Then, by pressing a protrusion of the heating plate or a heating plate for cutting against substantially the central part of the bonded portion, local heat transfer takes place to sublime a resin component, whereby the separator is cut off. Thereupon, the pouch-shaped separator is attached to the electrode plate.

摘要： An alkaline secondary battery has a positive electrode plate having a predetermined shape, formed from a long-shaped electrode substrate. A manufacturing method thereof comprises an impurity detecting step for applying X-rays to the electrode substrate to acquire a transmitted image, and detecting based on the transmitted image whether a metal impurity particle made of a metal dissolved at a positive electrode potential and deposited at a negative electrode potential exists in the electrode substrate. The method includes a marking step for, when the metal impurity particle exists, applying a marking indicative of its particle-existing portion on the electrode substrate.
