PURPOSE:To improve the cycle life of an alkaline zinc storage battery by inhibiting the development of zinc dendrite and the formation of a passive state film on the surface of the zinc electrode by using an additive in addition to the oxide or hydroxide of indium in the zinc electrode. CONSTITUTION:At least one oxide or hydroxide selected from among the oxides or hydroxides of mercury, lead, bismuth and cadmium is mixed with the oxide or hydroxide of indium in a ratio of 2-9. As a result, the development of zinc dendrite is inhibited by indium and the formation of a passive state film on the surface of a zinc electrode 1 is inhibited. Consequently, an increased cycle life of an alkaline zinc storage battery can be achieved. |
