Uniform Co3V2O8 microspheres via controllable assembly for high performance lithium-ion battery anodes

Abstract

As recently explored lithium ion batteries (LIBs)anode materials, transition metal vanadates have attracted much attention for their excellent electrochemical performance. In this work, we successfully synthesized solid Co3V2O8 microspheres (sCVO MSs) via a facile and controllable hydrothermal reaction, and the magical formation mechanismwas also revealed by the different morphology of sCVO MSs at different reaction time. When tested as LIBs anode materials, sCVO MSs showed superior reversible capacity (~780mAhg-1 after 250 cycles at 1000 mAg-1 and as high as 550mAhg-1 even after 400 cycles at 5000mAg-1), and excellent rate performance (capacity of ~500 mAhg-1 at the current density of 2000 mAg-1). It is accordingly demonstrated that the uniform sCVO MSs has great potential to be used as high-performance LIBs anodes.
