摘要： There is disclosed an electrode cartridge for use in a hermetic zinc secondary battery comprising a separator structure including a separator exhibiting hydroxide ion conductivity and water impermeability; a counter member liquid-tightly sealed to the separator structure so as to form an internal space and constituting an open-top water impermeable case together with the separator structure; and an electrode that is accommodated in the internal space of the water impermeable case and is a negative electrode containing zinc and/or zinc oxide or a positive electrode. According to the present invention, there is provided an electrode built-in component that can reliably isolate the positive and negative electrodes from each other with a hydroxide ion conductive separator, in the form of an electrode cartridge that is easy to handle and manufacture and that is more advantageous for assembling a stacked-cell battery, while reducing the number of sealing joints.

摘要： The present invention provides a sequential and efficient method of assembling a battery with a desired number of layers while reliably separating positive and negative electrode sides from each other with one or more separator structures. According to the invention, the method of assembling a battery includes stacking one or multiple combinations each comprising a frame and a positive electrode plate to be disposed in a region defined by the frame and one or multiple combinations each comprising a frame and a negative electrode plate to be disposed in a region defined by the frame, once or alternately, such that the positive and adjacent negative electrode plates are separated from each other by a separator structure and the periphery of the separator structure is held between the adjacent frames. The separator structure includes a separator exhibiting hydroxide ion conductivity and water impermeability.

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 hydroxide-ion-conductive dense membrane having a He permeability per unit area of 10 cm/min·atm or less. The present invention provides a highly-densified hydroxide-ion-conductive membrane that can significantly reduce permeation of substances other than hydroxide ions (in particular, Zn, which may cause growth of dendritic zinc in a zinc secondary battery) and that is particularly suitable for use in, for example, a separator for a battery (in particular, a zinc secondary battery, which may cause growth of dendritic zinc).
