Electrical storage devices having excellent low-temperature properties can be obtained by using a quaternary salt (or ionic liquid) of general formula (1) below as an electrolyte salt for electrical storage devices or a liquid electrolyte for electrical storage devices.
In formula (1), R1 to R4 are each independently an alkyl group of 1 to 5 carbons or an alkoxyalkyl group of the formula R'-O-(CH2)n-, with the proviso that at least one group from among R1 to R4 is the above alkoxyalkyl group. X is a nitrogen or phosphorus atom, and Y is a monovalent anion.
An ionic liquid of general formula (1) below, e.g. for use as an electrolyte salt or a liquid electrolyte for electrical storage devices.
In formula (1), R1 to R4 are each independently an alkyl group of 1 to 5 carbons or an alkoxyalkyl group of the formula R' -O- (CH2)n-, with the proviso that at least one group from among R1 to R4 is the above alkoxyalkyl group, and two of the other groups form a ring. Y is a monovalent anion.

A liquid electrolyte for electrical storage devices, comprises an ionic liquid having general formula (1) below and a melting point of up to 50°C
wherein R1 to R4 are each independently an alkyl of 1 to 5 carbons or an alkoxyalkyl of the formula R'-O-(CH2)n-, R' being methyl or ethyl and the letter n being an integer from 1 to 4, and any two from among R1, R2, R3 and R4 may together form a ring, with the proviso that at least one of groups R1 to R4 is an alkoxyalkyl of the above formula; and Y is a monovalent anion. It may also include a nonaqueous organic solvent and/or an ion conductive salt.
