Template-free solvothermal synthesis of yolk–shell V2O5 microspheres as cathode materials for Li-ion batteries

Abstract

Uniform yolk-shell V(2)O(5) microspheres were synthesized via a facile template-free solvothermal route and subsequent calcination treatment in air. The resulting cathode materials showed a high specific capacity of 220 mA h g(-1) after 30 cycles and good rate capability.
