Anode and battery
First Claim
1. An anode, comprising:
- an anode current collector;
an anode active material layer being disposed on the anode current collector and being alloyed with the anode current collector in at least a part of an interface with the anode current collector; and
a coating including lithium carbonate on at least a part of a surface of the anode active material layer.

Abstract
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.
