Abstract
The invention concerns novel ionic compounds with low melting point whereof the onium type cation having at least a heteroatom such as N, O, S or P bearing the positive charge and whereof the anion includes, wholly or partially, at least an ion imidide such as (FX1O)N−(OX2F) wherein X1 and X2 are identical or different and comprise SO or PF, and their use as solvent in electrochemical devices. Said composition comprises a salt wherein the anionic charge is delocalised, and can be used, inter alia, as electrolyte.
Claims28
An ionic compound of low melting point having a cation of the onium type with at least heteroatom such as N, O, S or P bearing the positive charge and the anion including, in whole or in part, at least one imidide ion of the type (FX1O)N−(OX2F) wherein X1 and X2 are the same or different and comprise SO or PF.
A compound according to claim 4 wherein the polymerisation active group comprises double bonds, epoxides, or functions reactives in polycondensations.
