The present invention provides a battery that experiences a small degree of temporal change from the initial battery properties over the long term storage period of the battery. Specifically, the present invention provides a lithium secondary battery, in which a positive electrode capable of storing and releasing lithium and a negative electrode capable of storing and releasing lithium are formed via an electrolyte, wherein: the electrolyte comprises a cyclic solvent and a chain-type solvent and contains a compound having a boron-oxygen bond (B—O) and a carbon-carbon double bond (C═C).
