1. An electrolyte solution comprising a compound represented by the following formula (1):

OG Complex Work Unit Chemistry
wherein R101 and R102 are each individually a substituent represented by
—F,
a group represented by the formula:—Op101—(SiR1032O)n101—SiR1043, wherein R103 and R104 are each individually an alkyl group obtained by optionally replacing at least one hydrogen atom by a fluorine atom, an alkenyl group obtained by optionally replacing at least one hydrogen atom by a fluorine atom, an alkynyl group obtained by optionally replacing at least one hydrogen atom by a fluorine atom, or an aryl group obtained by optionally replacing at least one hydrogen atom by a fluorine atom; n101 is an integer of 0 or greater; and p101 is 0 or 1,
a C1-C7 alkyl group,
a C2-C7 alkenyl group,
a C2-C7 alkynyl group,
a C6-C15 aryl group,
—SO2X101, wherein X101 is —H, —F, or an alkyl group obtained by optionally replacing at least one hydrogen atom by a fluorine atom, with the proviso that, if one of R101 or R102 is —SO2X101, then the other of R101 or R102 is also —SO2X101,
—SO3X102, wherein X102 is —H, —F, or an alkyl group obtained by optionally replacing at least one hydrogen atom by a fluorine atom, or
a C2-C7 hydrocarbon group that forms a cyclic structure by bonding of R101 and R102, the cyclic structure optionally containing a multiple bond,
the substituent optionally contains at least one divalent to hexavalent hetero atom in a structure or optionally has a structure obtained by replacing at least one hydrogen atom by a fluorine atom or a C1-C7 functional group, and
at least one selected from the group consisting of R101 and R102, when both being an alkyl group, contains at least one divalent to hexavalent hetero atom in the structure or has a structure obtained by replacing at least one hydrogen atom by a fluorine atom or a C1-C7 functional group.
