Abstract
Provided is a separator structure for use in a zinc secondary battery. The separator structure includes a ceramic separator composed of an inorganic solid electrolyte and having hydroxide ion conductivity and water impermeability, and a peripheral member disposed along the periphery of the ceramic separator and composed of at least one of a resin frame and a resin film. The separator structure exhibits water impermeability as a whole. The separator structure of the present invention can reliably separate the positive electrode side from the negative electrode side in a zinc secondary battery, is readily sealed and bonded to a resin battery container, and exhibits significantly improved handleability during the assembly of the battery.
