Nanographene‐Constructed Hollow Carbon Spheres and Their Favorable Electroactivity with Respect to Lithium Storage

Abstract

Nanographene-constructed hollow carbon spheres (NGHCs) are fabricated using discotic nanographene as a building block and a silica/space/mesoporous silica sphere as a template. The resultant NGHCs exhibit uniform size and consist of dual walls. In the exterior walls of the NGHCs, 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 NGHCs show excellent electrochemical performance when used as anode material for lithium ion batteries.
