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.
