ABSTRACT:
A battery with a high capacity and superior cycle characteristics and an anode active material used for it are provided. An anode contains an anode active material capable of reacting with lithium. The anode active material contains tin, cobalt, and carbon, and further contains at least one from the group consisting of indium, niobium, germanium, titanium, molybdenum, aluminum, phosphorus, and bismuth. Further, in the anode active material, the carbon content is from 9.9 wt % to 29.7 wt %, and the ratio of cobalt to the total of tin and cobalt is from 30 wt % to 70 wt %. Further, coordination number of cobalt as a first neighboring atom around tin obtained by the radial structure function calculated based on one scattering theory of X-ray absorption spectroscopy is 4 or less.
