Abstract
The present invention provides a high-capacity sealed nickel-metal hydride storage battery superior in high-current discharge, without extending the injection time of an electrolyte. This battery includes an electrode group, a metal case for accommodating the electrode group, and a seal plate provided with a safety vent, for sealing an opening of the case, and the electrode group has a structure in which, round a non-sintered type cylindrical electrode of one polarity, a non-sintered type hollow cylindrical electrode of the other polarity and a non-sintered type hollow cylindrical electrode of the one polarity are layered alternately in the form of concentric circles with a separator between the electrodes.
