Abstract

Disclosed is an electrolyte solution for lithium secondary batteries, including a cyclic sulfonic acid ester represented by the general formula (1): wherein, in the general formula (1), Rand Reach independently represent a hydrogen atom, an alkyl group having 1 to 5 carbon atoms, halogen or an amino group with the proviso that Rand Rdo not represent hydrogen atoms at the same time; and Rrepresents methylene which may be substituted with fluorine. Batteries using this electrolyte solution are excellent in battery properties and storage characteristics.
