Facile synthesis of Zn3V2O8 nanostructured material and its enhanced supercapacitive performance

With a view to fabricate smart technology devices with portable features and with global energy security, researchers aimed to design high-performance electrode material to respond to the increasing demand for renewable energy storage systems. Nano Zn3V2O8 material was successfully synthesized via simple and low-cost chemical method. The structure and chemical conformation of the as-synthesized Zn3V2O8 were ascertained by physico-chemical techniques, respectively. BET results showed the mesoporous structure with specific surface area of 16 m2 g−1. Furthermore, its electrochemical performance was investigated in a three-electrode system. The as-synthesized Zn3V2O8 nanostructure exhibited high specific capacitance (Csp) of 471 F g-1 at 1 Acm−2 and cycling stability with 97% capacitance retention after 3000 cycles. The excellent performance of Zn3V2O8 nanostructure was related to its high conductivity and the fast electron/ions transportation. The unique features of Zn3V2O8 rendered it as superior electrode for energy storage systems.
