Abstract
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.
