NEGATIVE ACTIVE MATERIAL, NEGATIVE ELECTRODE EMPLOYING THE SAME, AND LITHIUM BATTERY EMPLOYING NEGATIVE ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide a negative active material, a negative electrode employing the same, and a lithium battery employing the negative electrode.SOLUTION: The present invention provides a negative active material, a negative electrode employing the same, and a lithium battery employing the negative electrode. The negative active material includes a composite core, and a coating layer formed on at least a part of the composite core. The composite core includes a carbonaceous base and a metal/metalloid nanostructure disposed on the base. The coating layer includes a metal oxide coating layer and an amorphous carbonaceous coating layer.
