Title:
METHOD FOR MANUFACTURING SEPARATOR/AIR ELECTRODE ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2018/163353
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a separator/air electrode assembly in which it is possible to carry out direct bonding while ensuring a desired adhesive strength of an air electrode layer containing LDH and CNT with respect to an LDH separator. This method includes: a step for preparing a layered double hydroxide (LDH) powder; a step for obtaining a metal oxide powder by baking the LDH powder at 400-850°C for 1-10 hours; a step for mixing a metal oxide powder, carbon nanotubes, and a solvent to form a paste or slurry; a step for applying the paste or slurry to the surface of the LDH separator; and a step for carrying out steam treatment of the LDH separator coated with the paste or the slurry, converting a metal oxide to LDH, and thereby obtaining an air electrode layer on the LDH separator.
