3D hollow Sn@carbon-graphene hybrid material as promising anode for lithium-ion batteries

Abstract

A 3D hollow Sn@C-graphene hybrid material (HSCG) with high capacity and excellent cyclic and rate performance is fabricated by a one-pot assembly method. Due to the fast electron and ion transfer as well as the efficient carbon buffer structure, the hybrid material is promising in high-performance lithium-ion battery. © 2014 Xiaoyu Zheng et al.
