Summary: The high energy demand has led to extensive research on novel materials for energy sources and storage applications. Covalent organic frameworks (COFs) exhibit desirable characteristics such as long-range order, permanent porosity, tunable pore size, and ion diffusion pathways, making them competitive electrode materials. In this study, two COF aerogels were shaped into flexible electrodes (ECOFs) using a simple compression method, and a thorough electrochemical investigation was conducted to fabricate an electrochemical double-layer capacitor (EDLC). This energy storage system has garnered considerable interest due to its high-power density and long cycle life compared to batteries. The results demonstrated the exceptional performance of ECOFs as EDLC devices, with almost 100% capacity retention after 10,000 charge/discharge cycles and the highest areal capacitance (9.55 mF cm(-2)) in aqueous electrolytes at higher scan rates (1000 mV s(-1)) for COFs. Moreover, the hierarchical porosity observed in ECOFs enhances ion transport, facilitating fast interface polarization with low tau(0) values. This comprehensive study sheds light on the use of ECOFs as novel electrode materials for EDLC devices.
