摘要： Provided is a highly reliable nickel-zinc battery including a separator exhibiting hydroxide ion conductivity and water impermeability. The nickel-zinc battery includes a positive electrode containing nickel hydroxide and/or nickel oxyhydroxide; a positive-electrode electrolytic solution in which the positive electrode is immersed, the electrolytic solution containing an alkali metal hydroxide; a negative electrode containing zinc and/or zinc oxide; a negative-electrode electrolytic solution in which the negative electrode is immersed, the electrolytic solution containing an alkali metal hydroxide; a hermetic container accommodating the positive electrode, the positive-electrode electrolytic solution, the negative electrode, and the negative-electrode electrolytic solution; and the separator exhibiting hydroxide ion conductivity and water impermeability and disposed in the hermetic container so as to separate a positive-electrode chamber from a negative-electrode chamber. The alkali metal hydroxide concentration of the positive-electrode electrolytic solution differs from that of the negative-electrode electrolytic solution.

摘要： Provided is a highly reliable nickel-zinc battery including a separator exhibiting hydroxide ion conductivity and water impermeability. The separator is disposed in a hermetic container to separate a positive-electrode chamber accommodating a positive electrode and a positive-electrode electrolyte from a negative-electrode chamber accommodating a negative electrode and a negative-electrode electrolyte. The positive-electrode chamber has an extra positive-electrode space having a volume that meets 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 meeting a variation in amount of water in association with reaction at the negative electrode during charge and discharge of the battery. The nickel-zinc battery further includes a gas flow channel that connects the extra positive-electrode space to the extra negative-electrode space such that the spaces are in gas communication with each other.

摘要： Provided is a highly reliable nickel-zinc battery, which includes a separator exhibiting hydroxide ion conductivity and water impermeability. The separator is disposed in a hermetic container to separate a positive-electrode chamber from a negative-electrode chamber. The positive-electrode chamber has an extra positive-electrode space having a volume that meets part of a variation in amount of water in association with the positive electrode reaction, and the negative-electrode chamber has an extra negative-electrode space having a volume that meets part of a variation in amount of water in association with the negative electrode reaction. 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.
