摘要：
Secondary cells and electrical double-layer capacitors of excellent charge-discharge efficiency, stability and low-temperature properties can be obtained using nonaqueous electrolytes which contain an ionic liquid that has general formula (1) below and is liquid at not higher than 50° C. and an ion-conductive polymer. 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— (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 R1 to R4 is an alkoxyalkyl group of the above formula. X is a nitrogen atom or a phosphorus atom, and Y is a monovalent anion.
