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.
