Bimetallic Conductive Metal‐Organic Frameworks for Supercapacitors: Charge Transport Mechanisms and Design Strategies

Supercapacitors have garnered significant global interest due to their high power density, rapid charge-discharge rates, and exceptional cycling stability. Among emerging electrode materials, bimetallic conductive metal-organic frameworks (MOFs) are particularly notable for their efficient electronic and ionic charge transport and tunable structural properties. This review first elucidates the charge transport mechanisms in MOFs, including through-space, through-bond, and hopping charge transport. It then systematically examines key optimization strategies for enhancing their performance as electrode materials, including π-delocalization to achieve superior conduction, redox-boosted conductivity, and dimensional modulation. Furthermore, this review discusses the advanced applications of bimetallic conductive MOFs in supercapacitors, with a focus on structure-property relationships. By offering in-depth insights into the rational design of high-performance electrodes using bimetallic conductive MOFs, this review provides valuable guidance for future research aimed at scalable and efficient energy storage solutions.
