PURPOSE: A lithium powder and silicon oxide double layer anode is provided to cover irreversible capacity in case of charging and discharging. CONSTITUTION: A lithium powder and silicon oxide double layer anode contains silicon oxide(SiOx, 0.1<=x<=1.2)(112) which is applied on a front surface of a first current collector and lithium powder(114) which is placed on the other surface. The lithium secondary battery(100) comprises: cathode(110) part; anode part containing anode active materials; a separator(130) for separating anode and cathode; and a case containing the anode, cathode, and separator. |
