Anode active material hybridizing carbon nano fibers for lithium secondary battery |
摘要 |
The present invention is to provide anode active material hybridized with carbon nano fibers for lithium secondary battery prepared by following steps comprising, i) dispersing the nano size metal catalyst to the surface of anode material selected from graphite, amorphous silicon or the complex of graphite and amorphous silicon; and ii) growing the carbon nano fiber by chemical vapor deposition method, wherein carbon nano fibers are grown in a vine form and surround the surface of anode active material.
