Anode active material including a multilayer metal nanotube, anode including the anode active material, lithium battery including the anode, and method of preparing the anode active material

摘要

An anode active material, an anode including the anode active material, a lithium battery including the anode, and a method of preparing the anode active material. The anode active material includes: a multilayer metal nanotube including: an inner layer; and an outer layer on the inner layer, wherein the inner layer includes a first metal having an atomic number equal to 13 or higher, and the outer layer includes a second metal different from the first metal.
