A lithium salt is disclosed. The lithium salt includes a lithium ion and an anion represented by formula (I), n n n n n n n n n n wherein R1 to R5 are independently selected from hydrogen atom, cyano group, fluorine atom, and C 1 -C 5 alkyl group, in which the C 1 -C 5 alkyl group is substituted with at least one fluorine atom. The present invention further provides an electrolyte solution and a lithium battery containing the lithium salt to enable a high conductivity of the battery at a high temperature. |
