  "textContent": "The present invention provides a polymer gel electrolyte capable of inhibiting the cell expansion of a polymer secondary battery and improving the cycle characteristics and high-temperature storage characteristics of a polymer secondary battery. The present invention relates to a polymer gel electrolyte comprising an aprotic solvent; a supporting salt; a cyclic sulfonic acid ester which includes at least two sulfonyl groups; and a crosslinked polymer obtained by crosslinking a methacrylic acid ester polymer represented by general formula (1) below. In the general formula (1), n meets 1800",
