摘要： A plurality of positive electrode plates and negative electrode plates are stacked alternately upon one another with intervening separators therebetween, wherein lateral edges of the positive electrode plates protrude beyond the negative electrode plates on one side, and lateral edges of the negative electrode plates protrude beyond the group of positive electrode plates on the opposite side. Collector plates are brought in tight contact with respective lateral edges of the positive and negative electrode plates, and heat is applied to the collector plate on an opposite surface of the electrode plates from a non-contact type heat source at several locations in lines along a direction in which the electrode plates are stacked.

摘要： A battery pack is constructed with a plurality of battery modules. Each battery module comprises a plurality of prismatic cell cases having short lateral walls and long lateral walls and respectively accommodating elements for electromotive force, these cells being mutually coupled sharing their short lateral walls as partition walls, thereby constituting an integral battery case. Electrode terminals of positive and negative polarities are arranged at longitudinal opposite ends of the integral battery case. Projections and indentations for positioning the plurality of battery modules when coupling them together with their long side faces abutted each other to constitute the battery pack are formed substantially in the center of given cell cases positioned symmetrical with respect to the centerline in the lengthwise direction of the battery module.

摘要： A method for recycling a battery pack is provided that enables a degraded battery pack to be replaced at a low cost while maintaining the advantages of a conventional sealed-type nickel-metal hydride secondary battery as being free from maintenance or leak of an electrolyte. The battery pack accommodates a battery module having a plurality of cells, which are a sealed-type nickel-metal hydride secondary battery, combined with each other. When the battery pack is judged as being degraded in a market, the battery pack is collected from the market as a battery to be replaced; a cell or battery module judged as being degraded is renewed by adding an electrolyte thereto; the battery module is installed in the battery pack again; and the battery pack is supplied as a replacement battery.

摘要： A battery which has undergone initial charging and discharging is placed inside a sealed vessel, which is evacuated by a vacuum pump. After this evacuated state has been maintained for a while, the density of hydrogen gas within the sealed vessel is measured by a hydrogen density sensor, based on which the presence or absence of a gas escape from the battery is determined. The battery may be heated instead of subjecting it to charging and discharging.
