    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： A sealed rechargeable battery module wherein a safety vent device is provided to release the internal pressure of the battery when the pressure has reached a predetermined value. The safety vent device includes a valve case formed with a vent and a sealing protrusion surrounding this vent. A valve body inserted in the valve case includes a sealing portion that is brought in tight contact with the sealing protrusion, a rigid holder for supporting the sealing portion, a and a resilient portion for pressing the rigid holder toward the vent. A valve cover is formed with apertures for closing the upper open end of the valve case. In a state, the resilient portion of the valve body is compressed.

    摘要： A battery module is constructed with a plurality of prismatic cells. Each cell comprises a prismatic cell case having short lateral walls and long lateral walls, a group of electrode plates constituted by laminating a plurality of positive and negative electrode plates parallel to the long lateral walls of the cell case with intervening separators therebetween, and collector plates of positive and negative polarities, respectively bonded to the positive and negative electrode plates at lateral opposite ends of the group of electrode plates. Connection projections are formed on the collector plates, these being fitted into corresponding holes in the short lateral walls of the cell case, whereby the collector plates are fixed on the short lateral walls of the cell case.

    摘要： A battery module is provided which includes multiple rechargeable batteries coupled together. The battery module includes multiple prismatic cell cases having short lateral walls and long lateral walls arranged side by side. Adjacent short lateral walls are integral with each other. The battery module includes holes extending through the short lateral walls of the cell cases at upper edge portions. The battery module also includes a pair of frame fittings that have base ends and protruding portions in each of the cell cases for connecting two adjacent cell cases. The protruding portions of the pair of frame fittings extend into the through holes in the upper edge portions of the short lateral walls of the cell cases from both sides and are welded together. Positive and negative electrode collector plates in the cell cases are respectively attached to the base ends of the frame fittings. End frame fittings that have base ends and protruding portions for cell cases are located at both outer ends of the rechargeable battery for connecting the cell cases to outside terminals. Connection terminals that have protruding portions are connected to the end frame fittings at both outer ends of the rechargeable battery.
