Abstract: 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).

Abstract: Provided is a method of forming a layered double hydroxide (LDH) dense membrane on the surface of a porous substrate. The LDH dense membrane is composed of an LDH represented by the formula: M2+1-xM3+x(OH)2An−x/n·mH2O where M2+ represents a divalent cation. M3+ represents a trivalent cation, An− represents an n-valent anion, n is an integer of 1 or more, and x is 0.1 to 0.4. This method includes (a) providing a porous substrate, (b) evenly depositing, on the porous substrate, a nucleation material capable of providing a nucleus from which the crystal growth of the LDH starts; and (c) hydrothermally treating the porous substrate in an aqueous stock solution containing a constituent element of the LDH to form the LDH dense membrane on the surface of the porous substrate. The method of the present invention can form a highly-densified LDH membrane evenly on the surface of a porous substrate.
