Na0.282V2O5: A high-performance cathode material for rechargeable lithium batteries and sodium batteries

261We report the synthesis of Na0.282V2O5 nanorods by a facile hydrothermal approach with annealing treatment, which is then used as cathode for lithium batteries and sodium batteries. Specially, Na0.282V2O5 nanorods exhibit superior electrochemical performances including high specific capacity, excellent cyclic stability and high-rate capability. Importantly, it demonstrates the long-term cycling stability up to 1000 cycles at 0.3 A g−1 as sodium batteries cathode.
