COMPOSITE BINDER COMPOSITION FOR SECONDARY BATTERY, CATHODE AND LITHIUM BATTERY CONTAINING THE BINDER

摘要

Disclosed are a binder composition for a secondary battery, which includes a first fluorine-based binder containing a polar functional group; a second fluorine-based binder that does not contain a polar functional group; and a non fluorine-based binder including a repeated unit derived from an acrylic monomer, wherein the first fluorine-based binder is a vinylidene fluorine-based binder, and a positive electrode and a lithium battery including the binder composition.
