Abstract

The rapid development of portable electronics, electric vehicles, and renewable energy systems has heightened the demand for high-performance energy storage devices. In this study, a trimetallic Ni–Co–Ce coordination framework (CF) was successfully synthesized via a simple hydrothermal method and directly deposited onto nickel foam as an electrode for supercapacitor applications. Structural and morphological characterization revealed a hierarchical architecture of oval-shaped microcrystals decorated with chestnut-like protrusions, providing abundant electroactive sites and facilitating efficient ion transport. Electrochemical measurements, including cyclic voltammetry and galvanostatic charge-discharge tests, demonstrated moderate capacitive behavior with specific capacitances increasing from 0.74 F/g to 2.6 F/g over successive cycles. Although Coulombic efficiency decreased from 23.5% to 11.6%, the incorporation of Ce enhanced structural stability and improved electron transport within the framework. These results suggest that Ni-Co-Ce coordination frameworks are promising candidates for supercapacitor applications, and further optimization of material composition and cycling conditions may lead to improved energy storage performance.
