1. A cathode hybrid electrolyte for a solid secondary battery, the cathode hybrid electrolyte comprising
an ion conductor represented by Formula 1,
an ionic liquid, and
a lithium salt different from the ion conductor of Formula 1, wherein an amount of the ion conductor is in a range of about 0.1 parts by weight to about 50 parts by weight based on 100 parts by weight of the lithium salt

OG Complex Work Unit Chemistry
wherein, in Formula 1, X is an unsubstituted or substituted C6-C30 arylene group, an unsubstituted or substituted C2-C30 heteroarylene group, or —C(═O)O—R7—;
R7 is an unsubstituted or substituted C1-C30 alkylene group or an unsubstituted or substituted C6-C30 arylene group;
R1 to R3 are each independently hydrogen, an unsubstituted or substituted C1-C20 alkyl group, an unsubstituted or substituted C6-C20 aryl group, or an unsubstituted or substituted C2-C30 heteroaryl group;
—Y− is an anionic moiety, wherein an anion of the ionic liquid comprises the same anionic moiety —Y− as in Formula 1;
n is a degree of polymerization, which is a number in a range of 10 to 500, and wherein the ion conductor represented by Formula 1 is a homopolymer.
