Abstract
Disclosed is a lithium secondary battery, including a cathode, an anode and a non-aqueous electrolyte, wherein the cathode includes a cathode active material containing lithium-metal oxide of which at least one of metals has a concentration gradient region between a core part and a surface part thereof, and the non-aqueous electrolyte includes a lithium salt, a polyfunctional nitrile compound and an organic solvent, such that the high-temperature storage and lifespan properties may be improved.
