The nickel-zinc battery of the present invention includes a separator exhibiting hydroxide ion conductivity and water impermeability. The separator is disposed in a hermetic container so as to separate a positive-electrode chamber accommodating a positive electrode and a positive-electrode electrolytic solution from a negative-electrode chamber accommodating a negative electrode and a negative-electrode electrolytic solution. The positive-electrode chamber has an extra positive-electrode space having a volume that meets at least part of a variation in amount of water in association with reaction at the positive electrode during charge and discharge of the battery, and the negative-electrode chamber has an extra negative-electrode space having a volume that meets at least part of a variation in amount of water in association with reaction at the negative electrode during charge and discharge of the battery. The battery further includes a gas-liquid flow channel that connects the extra positive-electrode space to the extra negative-electrode space, and the gas-liquid flow channel allows the electrolytic solution and gas in the positive-electrode and negative-electrode chambers to pass through the flow channel in response to a variation in amount of water caused by charge and discharge reactions.
