  "textContent": "An anode capable of preventing an increase in impedance and of improving cycle characteristics and a battery using the anode. The anode active material layer includes at least one kind selected from the group consisting of simple substances, alloys and compounds of silicon, germanium and tin, 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.",
