<P>PROBLEM TO BE SOLVED: To provide a nonaqueous electrolytic solution and an electrolyte for an electrochemical device, which allow the reduction in the generation of hydrogen fluoride caused by water in an electrolytic solution, and to provide an electrochemical device. <P>SOLUTION: The nonaqueous electrolytic solution comprises: a nonaqueous solvent; a nonaqueous electrolytic solution containing [B(CN)<SB POS="POST">4</SB>]<SP POS="POST">-</SP>as an electrolytic anion component dissolving in the nonaqueous solvent; and an electrolytic cation component expressed by the formula (1) which is dissolving in the nonaqueous solvent. In the formula, X represents a divalent saturated hydrocarbon group or a divalent heteroatom-containing saturated hydrocarbon group, forming a heterocyclic ring together with a nitrogen atom to which the hydrocarbon group is coupled, and Y represents a divalent saturated hydrocarbon group or a divalent heteroatom-containing saturated hydrocarbon group, forming a heterocyclic ring together with a nitrogen atom to which the hydrocarbon group is coupled. <P>COPYRIGHT: (C)2012,JPO&INPIT |
