Abstract
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), Rto Rare each independently an alkyl group of 1 to 5 carbons or an alkoxyalkyl group of the formula R'—O—(CH)— (R′ being methyl or ethyl, and the letter n being an integer from 1 to 4), and any two from among R, R, Rand Rmay together form a ring, with the proviso that at least one of Rto Ris an alkoxyalkyl group of the above formula. X is a nitrogen atom or a phosphorus atom, and Y is a monovalent anion.
