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

摘要

In this work, the V2O3 nanoparticles (NPs) with ultrathin carbon shells were synthesized by a facile solvothermal process. The V2O3 NPs were about 30 nm and contained a carbon shell of about 2 nm thick. The V2O3 NPs were homogeneously dispersed and loosely packed. When used as anode material, the V2O3 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. (C) 2018 Elsevier B.V. All rights reserved.
