HYBRID BATTERY BINDER

摘要

Disclosed is a composition comprising an ethylene copolymer and a polyetherimide, polyamideimide, polycarbonate, polyetheretherketone, polysulfone or polyethersulfone wherein the ethylene copolymer comprises or is produced from repeat units derived from ethylene and a comonomer selected from the group consisting of an α,β-unsaturated monocarboxylic acid or its derivative, an α,β-unsaturated dicarboxylic acid or its derivative, an epoxide-containing monomer, a vinyl ester, or combinations of two or more thereof; and the composition can further comprise a curing agent to crosslink the ethylene copolymer. The composition is useful as a binder for a lithium ion battery.
