摘要:
A plurality of positive electrode plates (18) and negative electrode plates (19) are stacked alternately upon one another with intervening separators (20) 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 (21, 22) 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 rectangular alkaline storage battery includes a plurality of rectangular positive electrode plates (1), negative electrode plates(2), and separators (3). The positive and negative electrode plates are layered alternately via the separators, resulting in a group of electrode plates. The group of electrode plates, together with an alkaline electrolyte, is housed in a rectangular container. In the battery, internal resistance is 5 mΩ or less, the electrode plate group thickness is 30 mm or less, and the amount of electrolyte is 1.3 to 8.0 g/Ah. This can achieve a rectangular alkaline storage battery that provides the optimum balance in the quantity of heat generation, heat release, and heat accumulation, high power, and excellent battery characteristics even when charged/discharged repeatedly and used for a long time.
摘要:
An alkaline rechargeable battery, having an electrode plate group (3) including positive electrode plates and negative electrode plates stacked alternately with separators interposed therebetween/ arranged in such a manner that a volume of the separators before the initial charge and discharge accounts for 30 to 60% of a volume of the electrode plate group (3).
摘要:
A battery module includes a plurality of cells (6) accommodating an electrode plate group (5) and an electrolyte, and a single integrated battery case (2) for accommodating the plurality of cells (6), the cells may be connected through lead portions protruding sideways on the lateral side of the cells. The ratio of the component resistance including the connecting resistance between the cells to the reactive resistance of the electrode plate group and the electrolyte in each cell, is set in the range of 1:99 - 40:60 at a temperature of 25°C. Thereby, the internal resistance per cell is reduced, and higher power output and improved service life characteristics are achieved.

摘要:
An alkaline storage battery having excellent self-discharge characteristics even after a number of charge-discharge cycles is provided. The alkaline storage battery is provided with a case 11 and an electrode group 12 enclosed in the case 11, and a separator that is included in the electrode group 12 retains at least 15 mg/cm 2 of an electrolyte at least in a period after assembling the battery, from the time the separator is impregnated with the electrolyte to the time the battery is activated.
