Title:
PREPARATION METHOD FOR NOVEL SOLID ELECTROLYTE
Document Type and Number:
WIPO Patent Application WO/2022/160824
Kind Code:
A1
Abstract:
The present invention belongs to the field of energy materials, relates to a preparation method for a novel solid electrolyte, and specifically relates to a method for preparing a porous powder material by means of in-situ polymerization of a polymer on the surface of cellulose nanocrystal, activating the porous powder material by means of an electrolyte solution and then performing hot pressing to form a film. According to the technical solution of the present application, the cellulose nanocrystal is used as a template, the powder material with the porous structure is prepared by means of in-situ polymerization growth of a polymer on the surface of the cellulose nanocrystal, the powder is activated by means of a small amount of electrolyte solution, and the solid electrolyte is prepared by means of hot-pressing film formation. The solid electrolyte prepared by using said method has excellent electrochemical performance and mechanical performance, and has a wide application prospect. Moreover, the technical solution provided by the present invention solves the problem that a large amount of toxic solvents are generated by means of traditional solution evaporation film formation, and is more environmentally friendly and efficient.
