ANODE COMPRISING METAL NANOTUBE, LITHIUM BATTERY COMPRISING ANODE, AND PREPARATION METHOD THEREOF

摘要

PURPOSE: A negative electrode comprising metal nanotube, a lithium battery comprising the same, and a preparation method thereof are provided to improve the discharge capacity, capacity retention rate, charge and discharge efficiency, and high efficiency of a lithium battery. CONSTITUTION: A negative electrode comprises: a conductive substrate; and nanotubes comprising a metal/metalloid, disposed on the conductive substrate, and having opened ends. The nanotubes comprise one selected from the group consisting of silicon(Si), germanium(Ge), tin(Sn), aluminum(Al), zinc(Zn), silver(Ag), gold(Au), platinum(Pt), and an alloy thereof. The nanotubes further comprise a dopant.
