PURPOSE:To improve the initial activity, utilization factor, and life characteristic by applying high-temperature alkaline treatment to a hydrogen storage alloy electrode. CONSTITUTION:A hydrogen storage alloy expressed by ZrMn0.6Co0.1V0.2Ni1.2 which is one of C15 type Laves-phase alloys is molded into an electrode, then it is dipped in a 31%-KOH solution at 100 deg.C for 2hr, for example. This electrode is used for a negative electrode, a well-known nickel oxide electrode is used for a positive electrode to constitute a battery, the initial activity is sharply improved, and the utilization factor and life characteristic are improved. |
