A secondary battery including: an anode (110) including a positive electrode active material (130); a cathode (200) including a negative electrode active material (230); a separator (300) interposed between the anode (100) and the cathode (200); and a non-aqueous electrolyte. The positive electrode active material includes a lithium nickel oxide, and the negative electrode active material includes at least one silicon compound selected from the group consisting of silicon, a silicon oxide, and a silicon alloy. |
