Binder having high adhesion for carbon-coated lithium iron phosphate electrode, electrode containing same, and lithium secondary battery containing same

Abstract

The present disclosure provides a polymer binder for a secondary battery electrode, which serves as a binder for a carbon-coated lithium iron phosphate (c-LiFePO4) electrode and is a copolymer containing a hard segment capable of hydrogen bonding in the electrode and a soft segment having a polyol structure. Also, the present disclosure provides a secondary battery electrode and a lithium secondary battery containing the same, wherein a nonaqueous electrolyte solution is applied to an electrode mixture containing the binder for an electrode.
