Fast synthesis of Co1.8V1.2O4/rGO as a high-rate anode material for lithium-ion batteries†
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.
