LDH-LIKE COMPOUND SEPARATOR AND ZINC SECONDARY BATTERY

Provided is an LDH-like compound separator including a porous substrate made of a polymeric material; and a layered double hydroxide (LDH)-like compound with which pores of the porous substrate are plugged. A central region along the thickness of the LDH-like compound separator has a lower mean porosity than peripheral regions along the thickness of the LDH-like compound separator.
