| titleOfInvention | Anode Active Material for Lithium Secondary Battery Hybridized with Carbon Nanofibers |
| abstract | The present invention provides a negative electrode active material for a lithium secondary battery prepared by dispersing a catalyst on an active material surface selected from graphite, amorphous silicon, or a composite of graphite and amorphous silicon, and vapor-growing carbon nanofibers in the presence of a carbon source. The present invention provides a negative electrode active material for a lithium secondary battery in which carbon nanofibers are grown by vapor deposition on an active material supported by catalyst particles, and the carbon nanofibers are hybridized into a structure surrounding the negative electrode active material in a vine form. The negative electrode active material for a lithium ion secondary battery manufactured according to the present invention exhibits a feature of uniformly growing conductive carbon nanofibers on the surface of an active material particle to surround the surface like a vine, thereby forming an electrode active material structure. Since the volume expansion can be suppressed, it is possible to provide excellent cycle characteristics even under high rate charge and discharge conditions. n n Carbon nano fiber, hybrid, natural graphite, silicon, vine structure, lithium ion secondary battery, negative electrode material, herringbone, plate |
