High-Efficiency Aqueous Zinc-ion Capacitors Based On Mofs/cofs-derived Nanomaterials: Challenges and Future Prospects

Aqueous zinc-ion capacitors have garnered significant attention recently due to their safety, environmental benefits, and high capacity. However, its practical application still faces many challenges. Metal–organic frameworks (MOFs) and Covalent organic frameworks (COFs)-derived nanomaterials have demonstrated outstanding potential as electrode materials due to their unique structure and adjustable properties. Here, the current application status of MOFs/COFs-derived nanomaterials in high-efficiency aqueous ZICs is reviewed and the structure and properties of these materials, as well as their synthesis methods and advantages in capacitors are explored. The key factors influencing the properties of aqueous ZICs, including material structure, morphology, electrochemical characteristics, stability, and cycle life, are further examined. Although there are current challenges in the controllability of material preparation, large-scale production, electrolyte and electrode interface, the future development of aqueous ZICs is promising through new material design and synthesis strategies, performance optimization, and interdisciplinary research. This paper examines the future research directions and application potential of MOFs/COFs-derived nanomaterials in waterborne ZICs.
