The selection of appropriate electrode materials and electrolytes in addition to optimization of their combinations is a key to improve the performance of supercapacitors. Among the new electrode materials, metal‐organic frameworks (MOFs) based electrodes are attracting attention in energy storage devices, including supercapacitors and batteries. In recent years, the redox additive electrolytes have been projected as efficient options over simple aqueous electrolytes. The present work reports the synthesis of a layered MOF, i. e., manganese‐1,4‐ benzene dicarboxylate (Mn‐BDC) and explores its utility as a supercapacitor electrode in the presence of an optimized redox additive electrolyte (0.2 M K3[Fe(CN)6] in 1 M Na2SO4 (0.2 M KFCN)). As demonstrated for the first time in this study, the combined use of the porous Mn‐BDC electrode and KFCN electrolyte has provided a synergistic enhancement in the supercapacitor performance. The present Mn‐BDC/KFCN combination has delivered a high specific capacitance of 1590 F/g at a current density of 3 A/g. Furthermore, the Mn‐BDC electrode could retain around 82% of its initial specific capacitance even after 3000 continuous charge‐discharge cycles. In view of its encouraging electrochemical performance parameters, the proposed system can be touted as an efficient supercapacitor assembly.

“…Many characteristic bands of BDC (e. g., 528, 1692 and 2820 cm −1 corresponding to the δ(COO), ν(COO) and ν(OH) vibrations of the non‐ionized carboxyl groups) disappeared in the sample of Mn‐BDC. Importantly, a band at 752 cm −1 was an important indicator to suggest the successful coordination of Mn 2+ ions with BDC …”

“…Metal-organic frameworks (MOFs) including zeolitic imidazolate frameworks (ZIFs) with tunable metal centers and organic linkers are designed to meet various demands, including gas storage and separation, sensing, catalysis and drug delivery [3][4][5][6]. Recently, conjugated carboxylates based MOFs, such as Co-BDC [7,8], Mn-BDC [9], Fe-BDC [10,11], Mn-BTC [12], CoBTC [13], Cu-BTC [14] and Fe-BTC [15], are being employed in LIBs and have attracted tremendous attention for their high performances. Further researches indicate that lithium is inserted into organic moiety in these MOFs and it is deduced that the electron withdrawing effect of the conjugated carboxylates should be the main impetus in storing lithium-ions [12][13][14][15][16][17][18][19].…”

In this work, a bimetallic zeolitic imidazolate framework (ZIF) CoZn-ZIF was synthesized via a facile solvothermal approach and applied in lithium-ion batteries. The as-prepared CoZn-ZIF shows a high reversible capacity of 605.8 mA h g −1 at a current density of 100 mA g −1 , far beyond the performance of the corresponding monometallic Co-ZIF-67 and Zn-ZIF-8. Ex-situ synchrotron soft X-ray absorption spectroscopy, X-ray diffraction, and electron paramagnetic resonance techniques were employed to explore the Li-storage mechanism. The superior performance of CoZn-ZIF over Co-ZIF-67 and Zn-ZIF-8 could be mainly attributed to lithiation and delithiation of nitrogen atoms, accompanied by the breakage and recoordination of metal nitrogen bond. Morever, a few metal nitrogen bonds without recoordination will lead to the amorphization of CoZn-ZIF and the formation of few nitrogen radicals.

Metal-organic frameworks (MOFs) and their derivatives are two developing families of functional materials for energy storage and conversion. Their high porosity, versatile functionalities, diverse structures, and controllable chemical compositions offer immense possibilities in the search for adequate electrode materials for rechargeable batteries. Despite these advantageous features, MOFs and their derivatives as electrode materials face various challenging issues, which impede their practical applications. From this perspective, we present both the opportunities and challenges that MOFs/MOF composites and MOF-derived materials bring to rechargeable batteries, including lithium-ion batteries, lithium-sulfur batteries, lithium-oxygen batteries, and sodium-ion batteries. By discussing the development of MOFs/MOF composites and MOF-derived materials in each battery system, some design principles that dominate the specific electrochemical behaviors are outlined, with the key requirements that a practical electrode should fulfill. At the end, a basic guidance and future directions for further development are provided.
