摘要： Provided is a gel polymer electrolyte comprising a diacrylamide compound as a precursor for formation of a crosslinked polymer.
The gel polymer electrolyte in accordance with the present invention enables improvements of the battery safety by significant reduction of thickness swelling of the battery to thereby prevent the electrolyte leakage, while simultaneously preventing deterioration of charge-discharge rate characteristics and cycle characteristics which may occur upon use of a gel-type electrolyte.
