Title:
SEPARATOR STRUCTURE, NICKEL-ZINC SECONDARY BATTERY, AND ZINC-AIR SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2018/135117
Kind Code:
A1
Abstract:
Disclosed is a separator structure for a zinc secondary battery. This separator structure is provided with: a composite plate comprising a layered double hydroxide (LDH) separator and a porous substrate provided to one side of the LDH separator; and a resin outer frame having an opening in which the composite plate is to be fitted. The resin outer frame has a recess for locking the porous substrate side of the composite plate along the inner periphery of the resin outer frame, and the recess and the composite plate are seal-jointed with an adhesive. The porous substrate has a thickness of at least 100 μm, and the portion of the porous substrate that faces the recess is impregnated with the adhesive down to a depth of at least 100 μm from the surface of the porous substrate. The present invention makes it possible to improve reliability and durability of a separator structure in which a porous substrate-equipped LDH separator is provided in a resin outer frame.
