Template‐Free Synthesis of VO2 Hollow Microspheres with Various Interiors and Their Conversion into V2O5 for Lithium‐Ion Batteries

Getting a charge out of microspheres: Uniform VO2 microspheres with various complex interiors, such as yolk-shelled and multi-shelled hollow structures, have been synthesized through a template-free solvothermal method. After annealing in air, the derived V2O5 microspheres manifest improved electrochemical performance as a high-capacity cathode material for lithium-ion batteries.
