Organic electrolyte solution and lithium battery including the same

Abstract

An organic electrolyte solution includes a lithium salt; an organic solvent; and a fluorine-containing phosphate compound represented by Formula 1: wherein, in Formula 1, R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, and R15 are each independently a hydrogen atom, a fluorine atom, a C1-C5 alkyl group substituted or not substituted with a halogen atom, a C4-C10 cycloalkyl group substituted or not substituted with a halogen atom, a C6-C10 aryl group substituted or not substituted with a halogen atom, a C2-C10 heteroaryl group substituted or not substituted with a halogen atom, or a C2-C10 alkenyl group substituted or not substituted with a halogen atom, at least one of R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, or R15 is a fluorine atom, and at least one phenyl group does not have a fluorine atom.
