ABSTRACT:
Provided is a battery capable of obtaining a superior battery capacity and a superior charge-discharge cycle characteristic under high temperature conditions, and improving a load characteristic. A laminate including a cathode (21) and an anode (22) with a separator (23) in between is spirally wound. The cathode (21) includes a cathode mixture layer which includes a lithium-containing complex oxide including at least one kind selected from the group consisting of Co, Ni, Mn and Fe. The anode (22) includes an anode mixture layer including a tin-containing alloy, a carbon material, and a fatty acid or a metal salt thereof. Thereby, a superior battery capacity and a superior charge-discharge cycle characteristic under high temperature conditions can be obtained. Moreover, when the content of the fatty acid or the metal salt thereof in the anode mixture layer is within a range from 0.1 wt % to 6 wt % inclusive, a load characteristic can be improved.
