Title:
METHOD FOR MANUFACTURING IONICALLY CONDUCTIVE LATP NANOFIBER WEB
Document Type and Number:
WIPO Patent Application WO/2024/090834
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing an ionically conductive nanofiber web through firing after electrospinning a spinning solution containing a metal salt and a polymer. According to the present invention, it is possible to provide a LATP nanofiber web that has high ionic conductivity, high porosity, a small pore size, an interconnected open pore structure, high permeability, and a large surface area and has excellent thermal and chemical properties and mechanical strength, and thus can replace existing polymer microporous separation membranes of LIBs.
