Enhanced Electrochemical Performance in Supercapacitors through KCu−Cy Based Metal‐Organic Framework Electrodes
Abstract: In the realm of electronics and electric energy storage, the convergence of organic and metallic materials has yielded promising outcomes. In this study, we introduce a novel metal‐organic polymer synthesized from Cyamelurate and copper (KCu−Cy) and explore its application as an electrode for a supercapacitor. This material was pressed onto a stainless‐steel grid as a thin film and synthesized on nickel foam. Comprehensive characterization was carried out to confirm the synthesis, ensure phase purity, and investigate atomic interactions. Single Crystal X‐ray Diffraction (SCXRD) and Powder X‐ray Diffraction (PXRD) analyses verified the synthesis and phase purity, shedding light on atomic arrangements. Fourier Transform Infrared Spectroscopy (FTIR) analyses provided insights into characteristic peaks within the material. Thermal Gravimetric Analysis (TGA) gauged stability and durability. Electrochemical performance was assessed through cyclic voltammetry. Notably, the nickel‐supported electrodes, devoid of binders, exhibited exceptional specific capacity, reaching 1210.89 F/g at a scan rate of 5 mV/s, in contrast to 363.73 F/g for the pressed thin film on the stainless‐steel grid, which incorporated a conductive agent and binder. Cu−Cy displayed impressive cyclization resistance, with a capacity retention of 90 % even after 11000 cycles. These findings underline the promise of Cu−Cy as a high‐performance electrode material for supercapacitors, particularly in binder‐free configurations, and suggest its potential in advanced energy storage applications.
