Abstract
Official abstract text for this publication.
A composite anode active material, a method of preparing the composite anode active material, and a lithium battery including the lithium battery. According to the method of preparing the composite anode active material, carbon nanotubes are formed on a Si particle without a separate operation of applying a catalyst. Furthermore, high adherence is provided between the Si particle and carbon nanotubes, and therefore the composite anode active material is used as an anode material of the lithium battery.
First claim
Opening claim text (preview).
What is claimed is: 1. A composite anode active material comprising: a Si particle; a carbon layer surrounding a surface of the Si particle; and carbon nanotubes extended outwards from the carbon layer, wherein the carbon nanotubes are allotropes of carbon with a cylindrical nanostructure including a graphene layer wrapped into a cylinder. 2. The composite anode active material of claim 1 , wherein the carbon layer comprises at least one of a group con…
