Facile Preparation of Nb2O5@Carbon Hollow Microspheres as High-Performance Anode Materials for Lithium-Ion Batteries
Nb2O5@carbon hollow microspheres (Nb2O5@CHMs) have been synthesized through a facile hydrothermal method. Results revealed that numerous urchin-shaped Nb2O5 nanospheres were tightly and uniformly anchored on the surface
of carbon hollow microspheres. Nb2O5@CHMs with unique structure exhibited a high initial discharge capacity of 420.32 mA h·g−1 and an impressive reversible capacity of 350.15 mA h·g−1 after 100 cycles at the current density
of 40 mA·g−1. The Nb2O5@CHMs is a potential high-performance anode material for lithium ion batteries.
