Abstract
It is an object of the present invention to provide a material for electrolytic solutions suited for use as material in electrolytic solutions serving as ionic conductors in electrochemical devices, such as large-capacity cells or batteries. The present invention is related to a material for electrolytic solutions which comprises, as an essential constituent, an anion represented by the general formula (1): wherein X represents at least one element selected from among B, N, O, Al, Si, P, S, As and Se; M1 and M2 are the same or different and each represents an organic linking group; a is an integer of not less than 1, and b, c and d each independently is an integer of not less than 0.

A material for electrolytic solutions which comprises, as an essential constituent, an anion represented by the general formula (1) and an onium cation:
- wherein X represents at least one element selected from among B, N, O, Al, Si, P, S, As, and Se;
- M1 and M2 are the same or different and each represents an organic linking group selected from the group consisting of —S—, —O—, —SO2— and —CO2;
- a is an integer of not less than 1, b is 0, c is 0 and d is an integer of not less than 0, and wherein said onium cation is selected from the group consisting of
- wherein R is a C1-C8 alkyl group and each of R1 to R12 independently is a hydrogen atom, a cyano group, a sulphone group or a C1-C8 hydrocarbon group.
A material for electrolytic solutions which comprises an ionic liquid and an alkali metal salt and/or an alkaline earth metal salt and in which the mixture of the ionic liquid and the alkali metal salt in said material for electrolytic solutions shows a viscosity of not higher than 100 mPa·s,
- wherein the ionic liquid comprise an anion represented by the general formula (1) and an onium cation:
- wherein X represents at least one element selected from the group consisting of B, N, O, Al, Si, P, S, As and Se;
- M1 and M2 are the same or different and each represents an organic linking group selected from the group consisting of —S—, —O—, —SO2— and —CO2;
- a is an integer of not less than 1, b is 0, c is 0 and d is an integer of not less than 0, and wherein said onium cation is selected from the group consisting of
- wherein R is a C1-C8 alkyl group and each of R1 to R12 independently is a hydrogen atom, a cyano group, a sulphone group or a C1-C8 hydrocarbon group.
