An object of the present invention is to provide a novel quaternary ammonium-based room temperature molten salt useful as an electrolyte, an electrolytic solution, and a solvent for organic synthesis of electrochemical devices such as a secondary battery and an electric double layer capacitor. A quaternary ammonium-based room temperature molten salt represented by the following general formula (1). Embedded image (In the formula, R 1 and R 2 each independently represent a hydrogen atom, a methyl group, or an ethyl group, and R 3 to R 5 each independently represent an alkyl group having 1 to 4 carbon atoms. O—, —NR 6 —, or —S—, which may include a plurality of these atomic groups, wherein R 6 represents a hydrogen atom, a methyl group, or an ethyl group, and n is an integer of 1 to 3. And A represents an anion.) [Selection diagram] None |
