PURPOSE:To improve a service life characteristic by specifying concentration of an OH<-> ion in electrolyte in a nickel-zinc battery. CONSTITUTION:In a nicke-zinc battery formed by using a microporous film separator having air permeability of 2-500 sec/100cc, Concentration of an OH<-> ion in electrolyte is set within range of 2-8mol/l. Thereby, the nickel-zinc battery having a long service life can be formed, so that an industrial value can be improved. |
