ABSTRACT:
Disclosed is an alkaline storage battery using a negative electrode formed of a hydrogen absorbing alloy capable of absorbing/desorbing hydrogen electrochemically. A three-dimensional structural matter having hydrophobic property is used as a supporter for supporting the hydrogen absorbing alloy of the negative electrode, so that hydrophobic property is given to the surface of the hydrogen absorbing alloy which is in contact with the support, whereby a hydrogen gas generated in a charging period is absorbed by powder of the alloy exposed at a gas phase portion to suppress the increase of the internal gas pressure of the battery.
According to the present invention, it is possible to perform rapid charge in a short time because the increase of the internal gas pressure of the battery can be suppressed.
