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

摘要

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.
