1. An electrolyte comprising:
a polymer comprising a repeating unit represented by Formula 1; and a lithium salt,wherein, in Formula 1,  is a 5- to 31-membered group comprising X, 1 to 30 carbon atoms, and optionally at least one heteroatom,
wherein the 5- to 31-membered group comprises an unsubstituted or substituted C1-C30 cycloalkyl ring, an unsubstituted or substituted C1-C30 heterocycloalkyl ring, an unsubstituted or substituted C6-C30 aryl ring, or an unsubstituted or substituted C2-C30 heteroaryl ring, X is —S(═O)2—, —O—S(═O)2—O—, —O—S(═O)2—, —S(═O)2—O—C(═O)—O—S(═O)2—, or —S(═O)2—O—S(═O)—O—S(═O)2—, Z1 and Z2 are each independently O or S, Y is a covalent bond, an unsubstituted or substituted C1-C30 alkylene group, an unsubstituted or substituted C6-C30 arylene group, an unsubstituted or substituted C3-C30 heteroarylene group, an unsubstituted or substituted C4-C30 cycloalkylene group, or an unsubstituted or substituted C3-C30 heterocycloalkylene group, R1 to R8 are each independently a hydroxy group, a hydrogen atom, an unsubstituted or substituted C1-C30 alkyl group, an unsubstituted or substituted C1-C30 alkoxy group, an unsubstituted or substituted C6-C30 aryl group, an unsubstituted or substituted C6-C30 aryloxy group, an unsubstituted or substituted C3-C30 heteroaryl group, an unsubstituted or substituted C3-C30 heteroaryloxy group, an unsubstituted or substituted C4-C30 cycloalkyl group, or an unsubstituted or substituted C3-C30 heterocycloalkyl group, 0
