Abstract

Nanographene-constructed hollow carbon spheres (NCHCs) are fabricated using discotic nanographene as a building block and a silica/space/mesoporous silica sphere as a template. The resultant NCHCs exhibit uniform size and consist of dual walls. In the exterior walls of the NCHCs, nanochannels arrange perpendicularly to the surface, which is favorable for lithium ion diffusion from different orientations, while the interior graphitic solid walls can facilitate the collection and transport of electrons. The NCHCs show excellent electrochemical performance when used as anode material for lithium ion batteries. (Chemical Equation Persentation).
