Abstract
The present application provides a binder and a preparation method therefor, a secondary battery, a battery module, a battery pack and a power consuming device. The binder may comprise a copolymer C, and the copolymer C may comprise a structural unit derived from a monomer containing a cyano group, a structural unit derived from a monomer containing an ester group, and a structural unit derived from a monomer containing a group shown in formula I, in which n is selected from 0, 1, 2, or 3:
Claims19
A binder, comprising a copolymer C, wherein the copolymer C comprises a structural unit derived from a monomer containing a cyano group, a structural unit derived from a monomer containing an ester group, and a structural unit derived from a monomer containing a group shown in formula I,
- in which, n is selected from 0, 1, 2, or 3.
A preparation method for a binder, comprising the following steps:
- providing a monomer containing a cyano group, a monomer containing an ester group, and a monomer containing a group shown in formula I,
- in which, n is selected from 0, 1, 2, or 3;
- polymerizing the monomer containing a cyano group, the monomer containing an ester group, and the monomer containing a group shown in formula I to prepare a copolymer C under polymerizable conditions.
A power consuming device, comprising the battery pack according to claim 19.
