Patent ID: 8119038

Claim:
An organic electrolytic solution for a lithium battery comprising: a lithium salt; an organic solvent comprising a high dielectric constant solvent and/or a low boiling point solvent; a glycidyl ether compound selected from the group consisting of compounds represented by Formulae 1, 4-6 and 8-11 and combinations thereof: where: A is selected from the group consisting of a C2-C5 alkyleneoxide group which is unsubstituted or substituted with a halogen atom; —C(═O)—; and —C(R 7 )(R 8 )—, R 1 is selected from the group consisting of a C1-C20 alkoxy group which is unsubstituted or substituted with a halogen atom; a C6-C30 aryloxy group which is unsubstituted or substituted with a halogen atom; a C1-C20 alkyl group which is unsubstituted or substituted with at least one of a halogen atom and an oxirane group; a C5-C20 aliphatic hydrocarbon ring which is unsubstituted or substituted with a halogen atom; a C5-C20 aliphatic heterocyclic ring which is unsubstituted or substituted with a halogen atom; a C6-C30 aryl group which is unsubstituted or substituted with a halogen atom; a C7-C20 alkylaryl group which is unsubstituted or substituted with a halogen atom; a C7-C20 arylalkyl group which is unsubstituted or substituted with a halogen atom; a C2-C30 heteroaryl group which is unsubstituted or substituted with a halogen atom; an ether-containing monovalent group which is unsubstituted or substituted with a halogen atom; and —Si(R 9 )(R 10 )(R 11 ), R 2 , R 3 , R 4 , R 5 and R 6 are each independently selected from the group consisting of a hydrogen atom; a C1-C20 alkoxy group which is unsubstituted or substituted with a halogen atom; a C6-C30 aryloxy group which is unsubstituted or substituted with a halogen atom; a C1-C20 alkyl group which is unsubstituted or substituted with a halogen atom; and a C5-C20 aliphatic hydrocarbon ring which is unsubstituted or substituted with a halogen atom, R 7 and R 8 are each independently a hydrogen atom; or a C1-C20 alkyl group which is unsubstituted or substituted with a halogen atom, R 9 , R 10 and R 11 are each independently selected from the group consisting of a hydrogen atom; a C1-C20 alkoxy group which is unsubstituted or substituted with a halogen atom; a C6-C30 aryloxy group which is unsubstituted or substituted with a halogen atom; and a C1-C20 alkyl group which is unsubstituted or substituted with a halogen atom, wherein at least one hydrogen atom of at least one of R 1 through R 11 or A is substituted with a halogen atom; and n is an integer of 0-10;
