| 摘要 |
The invention relates to an electrolyte for an electrochemical device. This electrolyte includes an ionic metal complex represented by the general formula (1): <CHEM> wherein M is an element of groups 3-15 of the periodic table; A<a+> represents a metal ion, onium ion or proton; X<1> represents O, S or NR<5>R<6>; each of R<1> and R<2> independently represents H, a halogen, a C1-C10 alkyl group or C1-C10 halogenated alkyl group; R<3> represents a C1-C10 alkylene group, C1-C10 halogenated alkylene group, C4-C20 aryl group or C4-C20 halogenated aryl group; R<4> represents a halogen, C1-C10 alkyl group, C1-C10 halogenated alkyl group, C4-C20 aryl group, C4-C20 halogenated aryl group or X<2>R<7>; X<2> represents O, S or NR<5>R<6>; each of R<5> and R<6> represents H or a C1-C10 alkyl group; and R<7> 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. |
