Abstract
Disclosed is a lithium secondary battery. The lithium secondary battery includes a cathode, an anode, a separator and a non-aqueous electrolyte solution. Either the cathode or the anode or both include metal oxide coating layers on electrode active material particles forming the electrode or a metal oxide coating layer on the surface of an electrode layer formed on a current collector. The non-aqueous electrolyte solution contains an ionizable lithium salt, an organic solvent, and a dinitrile compound having a specific structure. In the lithium secondary battery, degradation of the electrode is prevented and side reactions of the electrolyte solution are inhibited. Therefore, the lithium secondary battery exhibits excellent cycle life and output performance characteristics.
