ABSTRACT:
A sealed alkaline storage battery with a long cycle life is disclosed, in which an inadequate adjustment between some of the electrode plates in a cell and the difference in the deterioration resulting from the difference in the heat dissipating abilities of the plates in the cell has been obviated. The storage battery comprises an electrode group configured by piling up a plurality of positive electrodes and a plurality of negative electrodes alternately with separators interposed therebetween, wherein the capacities of the respective negative electrodes are larger than those of the adjacent positive electrodes, except for the negative electrodes positioned at both ends of the electrode group. The capacities of the positive electrodes and the negative electrodes in the central part of the electrode group are larger than those of the positive electrodes and the negative electrodes located closer to both ends of the electrode group.
