Synthesis of micrometer hexagonal nanoplates of vanadium pentoxide as a cathode material for lithium ion batteries

Nanostructured vanadium pentoxide is synthesized via refluxing process, without any additional chemicals and reagents. Novel morphology of nanostructure is composed of micrometer hexagonal nanoplates which grow around nuclei in 3 dimensional. Thickness of nanoplates is less than 250 nm and diameter of hexagonal is about 5m. the results of X-ray diffraction reveals that ammonium vanadate nanostructure is composed in refluxing, and nanostructured V2O5 is gained in following annealing treatment of 400 C. The nanostructure as a cathode material for lithium ion batteries in combination with graphite and binder exhibits improving charge and discharge when cycling.
