Abstract
A battery capable of improving the energy density and cycle characteristics is provided. A cathode active material layer contains a complex oxide containing Li and Co as a cathode active material. An anode active material layer contains a CoSnC containing material containing Sn, Co, and C as an element, in which the content of C is from 16.8 wt % to 24.8 wt %, and the ratio of Co to the total of Sn and Co is from 30 wt % to 45 wt % as an anode active material. The surface density ratio of the cathode active material layer to the anode active material layer (surface density of the cathode active material layer/surface density of the anode active material layer) is from 2.77 to 3.90.
