Abstract

Layered LiV3O8 porous and hollow nanospheres were synthesized via a facile solid-phase oxidization and lithiation route with V2O3 hollow nanospheres as the precursor. When used as the cathode for Li-ion batteries, the as-obtained LiV3O8 porous and hollow nanospheres showed a high specific capacity of 324 mA h g−1 at a current density of 0.1 C, stable capacity (250 mA h g−1 after 50 cycles), and excellent rate capability (124 mA h g−1 at 5 C).
