| abstract |
The invention relates to an electrolyte for an electrochemical device. This electrolyte includes an ionic metal complex represented by the general formula (1): wherein M is an element of groups 3-15 of the periodic table; Aa+ represents a metal ion, onium ion or proton; X1 represents O, S or NR5R6; each of R1 and R2 independently represents H, a halogen, a C1-C10 alkyl group or C1-C10 halogenated alkyl group; R3 represents a C1-C10 alkyleme group, C1-C10 halogenated alkylene group, C4-C20 aryl group or C4-C20 halogenated aryl group; R4 represents a halogen, C1-C10 alkyl group, C1-C10 halogenated alkyl group, C4-C20 aryl group, C4-C20 halogenated aryl group or X2R7; X2 represents O, S or NR5R6; each of R5 and R6 represents H or a C1-C10 alkyl group; and R7 represents a C1-C10 alkyl group, C1-C10 halogenated alkyl group, C4-C20 aryl group or C4-C20 halogenated aryl group. The electrolyte has high heat resistance and hydrolysis resistance as compared with conventional electrolytes. |
