Unveiling the future of supercapacitors: Integrating metal–organic frameworks for superior energy storage

Amidst burgeoning energy demands, the integration of renewable energy sources, and the imperative of sustainability, the necessity for advanced energy storage technologies intensifies. Supercapacitors, strategically positioned between conventional capacitors and batteries, offer an alluring proposition owing to their swift charge–discharge capabilities and prolonged cycle longevity. This review delves into the fundamental role played by electrode materials in shaping the performance metrics of supercapacitors, with a focal point on Metal-Organic Framework (MOF) materials as prospective contenders. MOFs stand distinguished by their unparalleled surface area and adaptable characteristics, thus emerging as noteworthy alternatives to traditional activated carbons. Comparative analyses scrutinizing the electrochemical efficacy and sustainability facets of MOFs underscore their considerable potential within supercapacitor realms. The fusion of these materials holds promise in tackling energy storage challenges in a sustainable and efficacious manner. Ongoing scholarly endeavors are dedicated to refining their performance parameters, augmenting scalability, and expanding their application spectrum. This review engenders a comprehensive exploration of MOFs as electrodes for supercapacitors, epitomizing a transformative shift towards versatile, sustainable, and environmentally-conscious energy storage solutions.
