Facile template-free synthesis of uniform carbon-confined V2O3 hollow spheres for stable and fast lithium storage

Abstract

A facile template-free method has been successfully developed to synthesize uniform nitrogen-doped carbon-confined V₂O₃ hollow spheres by a mismatched coordination reaction, an inside-out Ostwald-ripening solvothermal process and subsequent heat treatment. Notably, the delicate composite as an anode material displayed superior rate capability and excellent cycling stability for lithium-ion batteries.
