Facile Synthesis of V(2)O(5) Hollow Spheres as Advanced Cathodes for High-Performance Lithium-Ion Batteries
Three-dimensional V(2)O(5) hollow structures have been prepared through a simple synthesis strategy combining solvothermal treatment and a subsequent thermal annealing. The V(2)O(5) materials are composed of microspheres 2–3 μm in diameter and with a distinct hollow interior. The as-synthesized V(2)...

description | Three-dimensional V(2)O(5) hollow structures have been prepared through a simple synthesis strategy combining solvothermal treatment and a subsequent thermal annealing. The V(2)O(5) materials are composed of microspheres 2–3 μm in diameter and with a distinct hollow interior. The as-synthesized V(2)O(5) hollow microspheres, when evaluated as a cathode material for lithium-ion batteries, can deliver a specific capacity as high as 273 mAh·g(−1) at 0.2 C. Benefiting from the hollow structures that afford fast electrolyte transport and volume accommodation, the V(2)O(5) cathode also exhibits a superior rate capability and excellent cycling stability. The good Li-ion storage performance demonstrates the great potential of this unique V(2)O(5) hollow material as a high-performance cathode for lithium-ion batteries. |
