Negative electrodes using hydrogen as an active material deteriorate as a result of volumetric changes during the charge/discharge process. Oxidation also causes deterioration thereof. Therefore, a negative electrode material for a battery was developed which is capable of storing hydrogen, contains a water-repellent hydrogen storage alloy and a hydrophilic hydrogen storage alloy, and uses hydrogen as an active material. Such a negative electrode material has high output properties, and is capable of a long service life by creating a hydrogen environment. In addition, it is possible to produce a negative electrode by using such a negative electrode material, and to assemble a battery with hydrogen as an active material thereof by using this negative electrode. The long-life battery having excellent high-output properties was developed by filling the interior of the battery with hydrogen gas after assembling the same. |
