Title:
BONDING COMPOSITION, ELECTRODE SLURRY, ELECTRODE SHEET, SECONDARY BATTERY AND ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/077507
Kind Code:
A1
Abstract:
The present application relates to a bonding composition, an electrode slurry, an electrode sheet, a secondary battery and an electric device. The bonding composition comprises a main body polymer and a cross-linking agent, wherein the main body polymer comprises structural units as shown in formulae (1)-(3), where X1 represents a structural group containing a first active group, and X2 is independently selected from H or an alkyl which has 1-10 carbon atoms at each appearance; and the first active group can chemically react with a functional group contained in the cross-linking agent, the functionality of the cross-linking agent being ≥2. When being used in the preparation of an electrode sheet, the bonding composition can improve the stability and the anti-cracking capacity of the electrode sheet, and thus can improve the cycling stability of a secondary battery.
