(002)-oriented WS2 with high crystalline with enhanced capacity as anode material for sodium ion batteries

(002)-oriented WS2 nanosheets with high crystalline have large interlayer spacing and high crystallinity. This crystal nanostructure is beneficial for improving capacity and stable capacity retention. The good electrochemical performance is attributed to (002)-oriented growth WS2 with large interlayer spacing and stable structure, accelerating Na+ insertion/extraction.579
