Abstract
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 oxide 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; the separator exhibiting hydroxide ion conductivity and water impermeability and disposed in the hermetic container to separate a positive-electrode chamber accommodating the positive electrode and the electrolytic solution from a negative-electrode chamber accommodating the negative electrode and the electrolytic solution; and a porous substrate on a surface of the separator facing toward the positive electrode.
