Efficient electrochemical performance of V2O5/SrO nanocomposite electrode for supercapacitor application

Abstract

A series of V₂O₅-SrO based nanocomposites introduced as a high-performing electrode material for supercapacitor applications. In this work, V₂O₅-SrO nanocomposites prepared through a simple hydrothermal process followed by thermal annealing method. The structural and morphological, elemental composition and functional groups of the composites examined through X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy and infrared spectroscopy. As the capacitive behaviour of V₂O₅-SrO composite electrode achieved, the specific capacitance of 931 F/g along with 90 % stability retention after 3000 cycles. Interestingly, the enhancing electrochemical properties mainly attributed to the emergence of the synergetic effect between the composite materials. These enhanced electrochemical characteristics of V₂O₅-SrO composite electrode promoted as a positive material for future electronic applications.
