摘要:
Provided is a secondary battery containing polyalkyleneglycol diglycidylether represented by formula I added in a predetermined amount to an electrolyte for the battery. The secondary battery containing the above additive exhibits remarkably improved high-temperature characteristics, prevents deterioration in rate characteristics and cycle characteristics, and considerably reduces thickness swelling of the battery so as to prevent battery leakage, ultimately enhancing safety of the battery.
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.
