Novel hierarchical three-dimensional ammonium vanadate nanowires electrodes for lithium ion battery

⿢Ammonium vanadate (NH4V4O10) nanowires grown on the Ti foil surface vertically.⿢The morphology of sample was changed with the amount of hexamethylenetetramine.⿢The sample deliver discharge capacity of 168.5 mA h g⿿1 at 2⿿4 V after 100 cycles.⿢The sample deliver discharge capacity of 330.5 mA h g⿿1 at 0.8⿿4 V after 100 cycles.
