1. An electrolyte comprising:
a lithium salt;
an organic solvent; and
at least one siloxane compound represented by Formula 1 or Formula 2,
wherein an amount of the at least one siloxane compound is 0.05 weight percent to 20 weight percent, based on a total weight of the electrolyte
wherein, in Formulae 1 and 2,

Y1 is hydrogen or —Si(R3)(R4)(R5),
n1 is an integer from 1 to 1000,
n2 is an integer from 1 to 5, and
R1 to R13 are each independently hydrogen, a substituted or unsubstituted C1-C10 alkyl group, a substituted or unsubstituted C6-C20 aryl group, or a polyalkylene oxide group represented by *—R31—O—(RO)m2—R32, wherein R31 is a substituted or unsubstituted C1-C10 alkylene group, and * represents a point of attachment to Si, RO is an alkylene oxide group, m2 is an integer from 1 to 20, and R32 is hydrogen or a substituted or unsubstituted C1-C10 alkyl group,
