A one-step synthesis of porous V2O3@C hollow spheres as a high-performance anode for lithium-ion batteries†
Abstract
Porous V2O3@C hollow spheres composed of ultrathin nanosheets were facilely fabricated via a one-step solvothermal route. When evaluated as an anode material, a large capacity of 583 mA h g−1 can be retained after 800 cycles at a current density of 2 A g−1, exhibiting excellent electrochemical performance.
