Cobalt vanadium oxide thin nanoplates: primary electrochemical capacitor application

摘要

Co₃V₂O₈ thin nanoplates are firstly described as a kind of electrode material for supercapacitors. More importantly, from electrochemical measurements, the obtained Co₃V₂O₈ nanoplate electrode shows a good specific capacitance (0.5?A g?1, 739?F g?1) and cycling stability (704?F g?1 retained after 2000 cycles). This study essentially offers a new kind of metal vanadium oxides as electrochemical active material for the development of supercapacitors.
