Document Type and Number:
WIPO Patent Application WO/2024/065165
Kind Code:
A1
Abstract:
Provided in the present application is a binder, which comprises a polymer and ceramic particles modified by a silane coupling agent. The polymer comprises structural units derived from a first-type monomer, a second-type monomer and a third-type monomer, and the molar ratio of the first-type monomer, the second-type monomer and the third-type monomer is 50-58: 40-44: 2-6, the first-type monomer being selected from one or more compounds of formula I, the second-type monomer being selected from one or more compounds of formula II, and the third-type monomer being selected from one or more compounds of formula III. The binder of the present application has improved bonding performance, and can improve the cyclic performance of secondary batteries.
