Abstract:
An electrolyte for an electrochemical device, said electrolyte comprising:a first compound that is an ionic metal complex represented by the general formula (1); and at least one compound selected from the group consisting of compounds corresponding to any one of the formulas whereinAa+ represents a metal ion, onium ion or hydrogen ion; M is a transition metal selected from the group consisting of elements of groups 3 11 of the periodic table, or an element selected from the group consisting of elements of groups 12-15 of the periodic table; a represents a number from 1 to 3; b represents a number from 1 to 3; p is b/a; m represents a number from 1 to 4; n represents a number from 0 to 8; q is 0 or 1; X1 represents 0, NR5 or NR5R6; R1 and R2 each independently represent H, a halogen, a C1-C10 alkyl group or C1-C10 halogenated alkyl group; R3 represents a C1-C10 halogenated alkylene group, C4-C20 arylene group or C4-C20 halogenated arylene group, wherein the alkylene and arylene groups of R3 optionally may carry substituents or include hetero atoms, and one group R3 optionally may be bonded with another group R3; R4 represents a halogen, C1-C10 alkyl group, C1-C10 halogenated alkyl group, C4-C20 aryl group, C4-C20 halogenated aryl group of X2R7, wherein the alkyl and aryl groups of R4 optionally may carry substituents or hetero atoms, and one group R4 optionally may be bonded with another group R4; X2 represents O, S, NR5 or NR5R6; R5 and R6 each independently represent H or a C1-C10 alkyl group; R7 represents a C1-C10 alkyl group, C1-C10 alkyl group, C1-C10 alkyl group, C1-C10 halogenated alkyl group, C4-C20 aryl group, or C4-C20 halogenated aryl group; x, y and z each independently represent a number from 1 to 8; Y1, Y2 and Y3 each independently represent an SO2 group or CO group; and R8, R9 and R10 each independently represent an electron-attracting organic substituent optionally carrying a substituent or including a hetero atom, wherein two or more of R8, R9 and R10 optionally may be bonded together to form a ring, and wherein one or more of R8, R9 and R10 optionally may be bonded with an adjacent molecule to form a polymer.
