GEL POLYMER ELECTROLYTE AND LITHIUM SECONDARY BATTERY COMPRISING SAME

摘要

The present invention relates to a gel polymer electrolyte and a lithium secondary battery comprising same, the gel polymer electrolyte comprising a polymer network and an electrolyte solution impregnated on the polymer network, wherein the polymer network is formed having an oligomer bound in a three-dimensional structure, the oligomer comprising: a unit A which is derived from a monomer comprising at least one or more of a copolymerizable acrylate or acrylic acid; a unit C which comprises urethane; and a unit E which comprises siloxane.
