title: Nb2O5microstructures: a high-performance anode for lithium ion batteries.
abstract: We report the synthesis of three-dimensional (3D) urchin-like Nb2O5microstructures by a facile hydrothermal approach with subsequent annealing treatment. As anode materials for lithium-ion batteries, the 3D urchin-like Nb2O5microstructures exhibit superior electrochemical performance with excellent rate capability as well as long-term cycling stability. The electrode delivers high capacity of 131 mA h g-1after 1000 cycles at a high current density of 1 A g-1. The excellent electrochemical performance suggests the 3D urchin-like Nb2O5microstructures may be a promising anode candidate for high-power lithium ion batteries.
