Title:
FLUOROPOLYMER, CONDUCTIVE PASTE, POSITIVE ELECTRODE PIECE, SECONDARY BATTERY AND ELECTRICAL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/092813
Kind Code:
A1
Abstract:
A fluoropolymer, a conductive paste, a positive electrode plate, a secondary battery, and an electrical apparatus. The fluoropolymer comprises a structural unit derived from a monomer represented by formula I and a structural unit derived from a monomer represented by formula II, wherein R 1 , R 2 , R 3 are each independently selected from one or more of hydrogen, fluorine, chlorine and fluorine-substituted C 1-3 alkyl, R 4 , R 5 are selected from hydrogen, substituted or unsubstituted C 1-5 alkyl, R 6 is selected from one or more of aryl-substituted C 1-5 alkyl, substituted or unsubstituted aryl. The fluoropolymer can improve the filterability of the conductive paste, improve the gel resistance and storage performance of the conductive paste, significantly broaden the process window of the conductive paste, and improve the machinability of the conductive paste.
