A simple method to prepare NH4V3O8 nanorods as cathode material for Li-ion batteries

NH4V3O8 nanorods have been synthesized by a facile water-bath method without template or surfactant. The as-obtained powder was characterized by XRD, indicating that this material was pure NH4V3O8. The electrochemical performance of NH4V3O8 as cathode material was investigated, which demonstrated th...

Description
Summary:NH4V3O8 nanorods have been synthesized by a facile water-bath method without template or surfactant. The as-obtained powder was characterized by XRD, indicating that this material was pure NH4V3O8. The electrochemical performance of NH4V3O8 as cathode material was investigated, which demonstrated that as-prepared NH4V3O8 electrode had a good lithium ion insertion/extraction ability with a specific discharge capacity of 238mAhg−1 at 15mAg−1. Moreover, it still maintained a high discharge capacity of 217mAhg−1 after 30 cycles, suggesting its promising application as the cathode material for Li-ion batteries. •A pure NH4V3O8 phase was synthesized by a facile water-bath method.•NH4V3O8 nanorods with a diameter of 30–50nm were obtained.•The NH4V3O8 electrode had a high discharge capacity and good cycling stability.
