Abstract
Al-doped ZnO nanoparticles (AZONs) have been successfully implanted in reduced graphene oxide (RGO) by a simple annealing process. The unique layered structure of composites is obtained, which is mainly ascribed to the well-anchored AZONs on the surface of RGO sheets. As anode materials for lithium ion batteries, the AZONs/RGO composites deliver an initial charge capacity of 624mAhg−1 and a 100th charge capacity of 391mAhg−1. Compared to pure AZONs, the remarkably enhanced reversible capacity and cycling stability of the composites could be attributed to the unique structure and the synergistic effect between the AZONs and RGO.
