The motivation for developing nanostructured electrode materials arises from the increasing demands of energy requirements of the upcoming generation due to excessive use of fossil fuels. The latest eco-friendly energy storage devices like supercapacitors that offers significant economic and environmental advantages, which possesses prolonged lifespan and a remarkable power density. In this study, structural evolution and electrochemical performance of BiFeO3@g-CN electrode material is characterized. The electrochemical properties of BiFeO3@g-CN are determined by using different analytical tests. The specific capacitance of pure BiFeO3 and BiFeO3@g-CN composite shows 557 and 1164 F/g, respectively calculating from galvanostatic charge-discharge plots. A number of factors, including the presence of several transition metal oxide, specific surface area (SSA), a nitrogen-rich structure of g-CN that allows quick ion transport which contributes to enhanced electrochemical efficiency. The material's structural stability was confirmed by its electrochemical stability after the 5000th cycle after 50 h. The BiFeO3@g-CN showed a lower charge transfer resistance (0.3 Ω) evaluated from electrochemical impedance spectroscopy analysis. The improvement in electrochemical properties of BiFeO3@g-CN electrode material indicates its potential suitability for integration into supercapacitors. The material's exceptional stability demonstrates its potential as a viable candidate for next-generation energy storage devices.
