The battery comprises a cylindrical type spirally wound body including a spirally wound laminate of a cathode and an anode with a separator in which an electrolyte solution is impregnated. The anode includes an anode current collector, an outer anode active material layer disposed on an outer winding surface of the anode current collector and an inner anode active material layer disposed on an inner winding surface of the anode current collector. The outer anode active material layer and the inner anode active material layer include Si, Sn or a compound thereof. As a capacity ratio between the outer anode active material layer and the inner anode active material layer in at least a region, assuming that the capacity of the outer anode active material layer is 1, the capacity of the inner anode active material layer facing the outer anode active material layer with the anode current collector in between is within a range of 0.6 to 0.8 inclusive.

摘要： Provided are an anode capable of preventing an increase in impedance and variations in characteristics and a battery using the anode. An anode active material layer includes at least one kind selected from the group consisting of simple substances, alloys and compounds of silicon and the like capable of forming an alloy with Li. The anode active material layer is formed by a vapor-phase deposition method or the like, and is alloyed with an anode current collector. A coating including lithium carbonate is formed on at least a part of a surface of the anode current collector. Thereby, an increase in impedance can be prevented. Moreover, the anode is less subject to an influence by a difference in a handling environment or storage conditions, so variations in impedance can be prevented.
