摘要：

In this work, nanoflower-like Na0.5VOPO4 center dot 2H(2)O with a large interlayer distance of 6.5295 angstrom is synthesized via a simple chemical precipitation method at room temperature. It is the first time that the potential of the Na0.5VOPO4 center dot 2H(2)O electrode as a cathode material for SIBs has been investigated, and it exhibits a high specific capacity (127 mA h g(-1) at 0.2C), outstanding long-term cycling stability and superior reaction kinetics.
