•NH4V4O10 nanorods for Na-ion battery cathodes.•Controllable the crystalline structure and morphology by metal nitrate.•High capacity and cycle stability.
A simple and versatile method for preparation of NH4V4O10 nanorods is developed via a simple hydrothermal route. NH4V4O10 nanorods display better cycling stability than NH4V4O10 microflowers as a cathode material for sodium-ion batteries because of the changes in crystalline structure, which would be in favor of superior discharge capacity. Furthermore, the enhancement of electrochemical performance for NH4V4O10 nanorods at high current rates is offered in addition of fluoroethylene carbonate to electrolyte. Such a good performance results from the improvement of reaction kinetics and Na-ion transfer rate.
