    摘要： A battery with a high capacity and superior cycle characteristics and an anode active material used in the battery are provided. An anode includes an anode active material capable of reacting with lithium. The anode active material includes at least tin, cobalt and carbon as elements, and the carbon content is within a range from 9.9 wt% to 29.7 wt% inclusive, and the ratio of cobalt to the total of tin and cobalt is within a range from 30 wt% to 70 wt% inclusive. Thereby, while a high capacity is maintained, cycle characteristics can be improved.
