Abstract
The present invention illustrates a conductive composite material, and a negative electrode materials and a secondary battery containing the same. The conductive composite material includes a core, an inner coating layer and an outer coating layer. The core is made of a first material selected from a group consisting of WA element, metal, metal compound or alloy. The inner coating layer is existed on the core and made of oxide, nitride or carbide of the first material. The outer coating layer is existed on the inner coating layer and made of a carbon material and a second material containing halogen or VA element.
