Abstract

A fast and facile approach to synthesize ultrasmall Co1.8V1.2O4 nanoparticles with an average size of 8.4 nm grown on rGO was successfully developed. The novel Co1.8V1.2O4/rGO composite anode exhibits excellent rate performance for lithium-ion batteries, delivering a high discharge capacity of 628 mA h g-1 at 2000 mA g-1.
