Kinetic and Thermodynamic Insights into Advanced Energy Storage Mechanisms of Battery-Type Bimetallic Metal–Organic Frameworks

The engineering of high-performance battery-type electrode materials highly depends on the guidance from combination experimental analysis and theoretical simulation. Herein, joint experimental–theoretical investigation provides a mechanistic explanation for electrochemical performance enhancement in bimetallic metal–organic frameworks (MOFs). superior CoNi-MOF our study exhibits advanced energy storage performance, achieving high specific capacity 382 C g–1 (1 A g–1), 2.0 1.4 times that Co-MOF Ni-MOF, respectively. Such significant results surface-controlled reaction kinetics low onset potential contributed by well-tuned electronic structures MOFs. Our opens up new perspectives understanding advantages mixed metal sites MOFs storage.
