LDH separator and zinc secondary battery

Abstract

To provide an LDH separator that can further improve the battery's cycle characteristics. [Solution] An LDH separator comprising at least one pair of porous substrates arranged facing each other, an intermediate layer provided between the at least one pair of porous substrates and containing a hydroxide ion-conducting layered compound which is a layered double hydroxide (LDH) and / or an LDH-like compound, and a pair of surface layers provided on the surfaces of the at least one pair of porous substrates away from the intermediate layer and containing a hydroxide ion-conducting layered compound.
