Polymer electrolyte composition for rechargeable lithium battery and rechargeable lithium battery including the same

摘要

A polymer electrolyte composition for a rechargeable lithium battery includes an acrylate-based polymer, a lactone-based compound having an alkyl substituent, a non-aqueous organic solvent, and a lithium salt. The electrolyte for a rechargeable lithium battery of the present invention exhibits excellent high temperature storage characteristics, excellent high temperature cycle-life characteristics, and improved safety without deteriorating cell performance.
