An electrolytic solution includes a compound containing a —CN functional group and a compound containing a silicon functional group. M is C or Si. R11, R12, and R13 are each independently selected from a substituted or non-substituted C1-C12 alkylene group, a substituted or non-substituted C2-C12 alkenylene group, an O—R group, an R0—S—R group or an R0—O—R group, R0 and R are each independently selected from a substituted or non-substituted C1-C6 alkylene group. n is 0 or 1. R14 is H, fluorine, a cyano group, a substituted or non-substituted C1-C12 alkyl group, a substituted or non-substituted C2-C12 alkenyl group, an O—R1 group, an R0—S—R1 group, or an R0—O—R1 group. R0 is a substituted or non-substituted C1-C6 alkylene group, and R1 is a substituted or non-substituted C1-C6 alkyl group.
