IONIC LIQUID CONTAINING PHOSPHONIUM CATION HAVING P-N BOND AND METHOD FOR PRODUCING SAME

摘要

Disclosed is an ionic liquid which contains an organic matter represented by the general formula (1) below as a cation component. This ionic liquid is stably in a liquid state over a wide temperature range while having excellent electrochemical stability. Consequently, the ionic liquid is useful for electrical storage devices, lithium secondary batteries, electric double layer capacitors, dye-sensitized solar cells, fuel cells, reaction solvents and the like.
