Abstract
(EN)
One aspect of the present invention is an electrolyte containing a compound represented by formula (1), and an cyclic compound not containing a silicon atom but having a ring which contains a sulfur atom. In formula (1), R1 to R3 independently represent an alkyl group or a fluorine atom, R4 represents an alkylene group, and R5 represents an organic group containing a sulfur atom.
(FR)
Selon un mode de réalisation, l’invention concerne une solution électrolytique qui comprend un composé représenté par la formule (1), et un composé cyclique exempt d'atome de silicium et ayant un cycle contenant un atome de soufre. Dans la formule (1), R à R représentent, chacun de manière indépendante, un groupe alkyle ou un atome de fluor, R représente un groupe alkylène, et R représente un groupe organique contenant un atome de soufre.
