A polymer gel electrolyte composition which comprises: a three−dimensionally crosslinked polymer network matrix containing an electrolyte solution in a nonaqueous solvent; and an uncrosslinked polymer contained in the matrix. The uncrosslinked polymer comprises (a) ethylene units and or propylene units and (b) units of an unsaturated carboxylic acid in which the carboxy group has been esterified with a polyalkylene glycol in which one of the terminal hydroxy groups has been protected. A polymer gel electrolyte composition which comprises: a three-dimensionally crosslinked polymer network matrix containing an electrolyte solution in a nonaqueous solvent and an uncrosslinked polymer contained in the matrix.

L'invention concerne une composition électrolytique en gel de polymères, qui comprend: une matrice tridimensionnelle d'un réseau de polymères réticulés contenant une solution d'électrolyte présente dans un solvant non aqueux; et un polymère non réticulé présent dans la matrice. Le polymère non réticulé comprend: a) des unités d'éthylène et/ou des unités de propylène; et b) des unités d'un acide carboxylique insaturé dans lequel le groupe carboxy a été estérifié avec un polyalkylèneglycol dont un des groupes hydroxy terminaux a été protégé.
