摘要: In this paper, layered vanadium pentoxide (V2O5) is employed as a cathode material for sodium ion battery. The V2O5 particle sizes range from 200 nm to 500 and the shapes of aggregated particles are non-homogeneous irregular. exhibits first discharge capacity approximately 208.1 mAh g−1. structure changes NaxV2O5 after Na+ insertion at discharge; remains stable␣during cycling. After 40 cycles, retains 61.2% second cycle. high charge/discharge current rate 1.0 C 49.1% 0.1 C. Furthermore, returns initial value results electrochemical performance tests indicate that potential batteries.
