“…The microwave synthesis method has the characteristics of being fast, efficient, and environmentally friendly, making it very attractive in MOF synthesis methods. A series of isostructural dual-ligand-based MOFs denoted as [M II 2 (H 2 O) 2 (4,4′-bipy)(mal) 2 ] n (M = Mn II , Co II , Zn II ) had been fabricated by a fast and facile microwave-heating technique . When utilized as LIB anodes, it was found that MOF metal centers had a significant impact on the performance of LIBs, with Co-MOF affording a higher efficiency than Mn and Zn homologues, maintaining an excellent specific capacity of 732 mA h g –1 after 200 cycles.…”

With the continuous growth of global energy demands and the increasingly serious environmental problems, the catalytic conversion and storage technology of sustainable energy has attracted more attention. Among the current energy storage methods, electrochemical energy storage (EES) is favored due to its high efficiency, stability, and environmental friendliness. In the development of EES devices, batteries and supercapacitors are the two most effective and attractive types. Metal−organic frameworks (MOF), as an emerging class of ordered crystal materials, are becoming highly promising electrode materials due to their adjustable topology structures, functionality, porosity, and electrocatalytic performances. The low conductivity seriously hinders the application of pristine MOFs in the field of energy storage, and a large number of MOF-based materials have been developed to meet the challenges of energy storage and conversion. Thus, the current review focuses mainly on the use of MOF-based materials (including pristine MOFs, MOF composites, and MOFderivatives) for EES, especially as electrode materials for metal-ion batteries and supercapacitors, and addresses the influence of material structures on electrochemical performances. Finally, we introduce the current challenges and improvement strategies of MOF-based electrode materials, pointing out the direction for developing electrode materials with industrial application value.

The construction of a thin, uniform, and robust solid electrolyte interphase (SEI) film on the surface of active materials is pivotal for enhancing the overall performance of lithium-ion batteries (LiBs). However, conventional electrolytes often fail to achieve the desired SEI characteristics. In this work, we introduced 1,3,6-hexanetrinitrile (HTCN) in the baseline electrolyte (BE) of 1.0 M LiPF6 in Ethylene Carbonate/Dimethyl Carbonate (EC/DMC) (3:7 by volume) with 5 wt.% fluoroethylene carbonate (FEC), denoted as BE-FH. By systematically investigating the influence of FEC: HTCN weight ratios on the electrochemical performance of graphite anodes, we identified an optimal composition (FEC:HTCN = 5:4 by weight, denoted as BE-FH54) that demonstrated greatly improved initial Coulombic efficiency, rate capability, and cycling stability compared with the baseline electrolyte. Deviations from the optimal FEC:HTCN ratio resulted in the formation of either small cracks or excessively thick SEI layers. The enhanced performance of BE-FH54-based LiB is mainly ascribed to the synergistic effect of FEC and HTCN in forming a robust, thin, homogeneous, and ion-conducting SEI. This research highlights the importance of rational electrolyte design in enhancing the electrochemical performance of graphite anodes in LiBs and provides insights into the role of nitrile-based additives in modulating the SEI properties.
