摘要

We report a facile method to topotactically synthesize Na1.25V3O8 nanowires with a novel hierarchical zigzag structure. The unique morphology can provide an increased electrode-electrolyte contact area and better strain accommodation; also the topotactic intercalation method can improve structure integrity and robustness. The assynthesized material delivers a capacity of 172.5 mA h g(-1) at 100 mA g(-1), shows excellent cyclability with a capacity fading of only 0.0138% per cycle at 1 A g(-1) for 1000 cycles, and high rate capability as a sodiumion battery cathode. We propose that the novel morphology as well as intrinsically advantageous structural features can synergistically facilitate the kinetics and stability, resulting in superior electrochemical performance.
