One-step solvothermal synthesis of V2O3@C nanoparticles as anode materials for lithium-ion battery

In this work, the V 2 O 3 nanoparticles (NPs) with ultrathin carbon shells were synthesized by a facile solvothermal process. The V 2 O 3 NPs were about 30 nm and contained a carbon shell of about 2 nm thick. The V 2 O 3 NPs were homogeneously dispersed and loosely packed. When used as anode material , the V 2 O 3 core-shell NPs showed a reversible capacity up to 525 mA h g −1 at 200 mA g −1 over 200 cycles with good cycle stability and rate capability. The excellent electrochemical performance promotes its practical application in lithium-ion batteries.
