▎ 摘  要

NOVELTY - Anode comprises an anode electrode current collector, a first anode active material layer formed on a surface of the anode current collector, where the first anode active material layer comprises a first anode active material comprising artificial graphite and first anode active material layer does not comprise carbon nanotube, and a second anode active material layer formed on the first anode material layer, where the second anode active material layer comprises a second anode active material including a silicon-based active material and carbon nanotube as a second conductive material. USE - The anode is useful for secondary battery such as lithium secondary battery, nickel-cadmium battery, and nickel-hydrogen battery. ADVANTAGE - The anode provides high-capacity property while obtaining sufficient life-span property and operational stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a lithium secondary battery.
