Kind Code:
A1
Abstract:
Disclosed in the present application is a waterborne binder. The binder comprises water-soluble enhanced polyvinyl alcohol grafted with a polyacrylic acid long branched chain or a copolymerization long branched chain of an acrylic monomer and an olefin monomer. The waterborne binder improves the defect that polyvinyl alcohol is easy to peel off and introduce air when dispersing a slurry. According to the preparation method, the long branched chain is precisely introduced; the cycling performance of a silicon-based anode having high gram capacity is improved, and the expansion of a pole piece is significantly inhibited.
