Document Type and Number:
WIPO Patent Application WO/2022/160381
Kind Code:
A1
Abstract:
A block polymer and a preparation method therefor and an application thereof, and a lithiated block polymer and a preparation method therefor and an application thereof. The block polymer has the structure shown in B-C-B-A, wherein A represents a polymer block A, B represents a polymer block B, and C represent a polymer block C; the polymer block A is formed by polymerization of an alkenyl formic acid monomer; the polymer block B is formed by polymerization of an aryl vinyl monomer; and the polymer block C is formed by polymerization of an acrylate monomer. The lithiated block polymer is a lithiated product of the block polymer. The block polymer and the lithiated block polymer may be used as a lithium-ion battery binder.
