Composites of V2O3–ordered mesoporous carbon as anode materials for lithium-ion batteries

The composites of V2O3–ordered mesoporous carbon (V2O3–OMC) were synthesized and used as anode materials for Li-ion intercalation. These materials exhibited large reversible capacity, high rate performance and excellent cycling stability. For instance, a reversible capacity of V2O3–OMC composites was 536 mA h g−1 after 180 cycles at a current density of 0.1 A g−1. The high electrochemical performance of the V2O3–OMC composites is attributed to the anchoring of nanoparticles on mesoporous carbon for improving the electrochemical active of V2O3 particles for energy storage applications in high performance lithium-ion batteries.
