Abstract
The invention relates to an ion-conducting material containing an oligoether sulfate. The material comprises an ionic compound dissolved in a solvating polymer. The ionic compound is a mixture of a lithium bis(trifluoromethanesulfonyl)imide and of at least one lithium oligoether sulfate chosen from the lithium oligoether monosulfates corresponding to the formula R—[O—CH—CH)]—O—SOLi(I) in which R is a group CHwith 1≦m≦4 and 2≦n≦17, and the lithium oligoether disulfates corresponding to the formula LiOSO—O—CH—[CH—O—CH]—CH—O—SO—OLi(II) in which 3≦p≦45; the overall ratio O/Liis less than or equal to 40, Orepresenting the total number of O atoms provided by the solvating polymer and by the oligoether; the content of LiTFSI is such that the O/LiTFSI ratio is greater than or equal to 20.
