A solid polymer electrolyte which comprises: a crosslinked polymer (I) obtained by crosslinking a composition comprising (i) a polyether copolymer having 5 to 95 mol% repeating units derived from a glycidyl compound 95 to 5 mol% repeating units derived from ethylene oxide and having a weight-average molecular weight of 105 to 107, (ii) a crosslinking agent selected between an organic peroxide and an azo compound, and (iii) a crosslinking aid which is an organic compound having a carbon-carbon double bond and an imide group; an electrolyte salt (II); and a plasticizer (III). It is excellent in mechanical properties and ionic conductivity.

L'invention se rapporte à un électrolyte polymère solide contenant un polymère réticulé (I) obtenu par réticulation d'une composition comportant (i) un copolymère de polyéther comportant, en pourcentage molaire, de 5 à 95 % d'unités récurrentes dérivées d'un composé glycidyle et de 95 à 5 % d'unités récurrentes dérivées d'oxyde d'éthylène et possédant un poids moléculaire moyen en poids compris entre 10?5¿ et 10?7¿, (ii) un agent de réticulation sélectionné parmi un peroxyde organique et un composé azoïque, et (iii) un adjuvant de réticulation qui est un composé organique possédant une double liaison carbone-carbone et un groupe imide; un sel pour électrolyte (II) et un plastifiant (III). Cet électrolyte est doté d'excellentes caractéristiques mécaniques et présente une excellente conductivité ionique.
