Title:
LDH-LIKE COMPOUND SEPARATOR AND ZINC SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2022/113448
Kind Code:
A1
Abstract:
Provided is a hydroxide ion conductive separator that has excellent alkali resistance, can more effectively suppress short circuiting caused by zinc dendrites, and is thus superior to LDH separators. This LDH-like compound separator includes: a porous substrate made from a polymer material; and a layered double hydroxide (LDH)-like compound that blocks the pores of the porous substrate. The average porosity of the central section of the LDH-like compound separator in the thickness direction is less than the average porosity of the section near the surface of the LDH-like compound separator.
