Abstract
A lithium secondary battery includes a cathode, an anode and a non-aqueous electrolyte. The anode includes an anode active material which contains a mixture of an artificial graphite and a natural graphite. A sphericity of the natural graphite is 0.96 or more. The lithium secondary battery including the anode has improved life-span and power properties.
