“…Additionally, Pingchun, Mengmeng, and Yanxiang have discovered the promising electrochemical properties of niobium monoxide, an NbO-type MOF incorporated with imidazolium-based IL with different sizes of alkyl chains and anion species [ 93 ]. The ionic conductivity values of BMIM-Cl@MOF and EMIM-Br@MOF at 150 °C were 6.63 × 10 −5 S cm −1 and 7.50 × 10 −6 S cm −1 , respectively.…”

Searching for a suitable electrolyte in a lithium-ion battery is a challenging task. The electrolyte must not only be chemically and mechanically stable, but also be able to transport lithium ions efficiently. Ionic liquid incorporated into a metal–organic framework (IL@MOF) has currently emerged as an interesting class of hybrid material that could offer excellent electrochemical properties. However, the understanding of the mechanism and factors that govern its fast ionic conduction is crucial as well. In this review, the characteristics and potential use of IL@MOF as an electrolyte in a lithium-ion battery are highlighted. The importance of computational methods is emphasized as a comprehensive tool to investigate the atomistic behavior of IL@MOF and its interaction in electrochemical environments.

“…The variable synthesis methods for IL/MOF composites and the ability to customize their physicochemical structures are responsible for their outstanding performances. There are two main fabrication methods for IL/MOF composites: ionothermal synthesis and postsynthesis modification. − To fabricate IL/MOF composites, ILs must be incorporated into MOFs, and this incorporation is possible for two reasons. On the one hand, the interaction between the IL and the MOF ensures that IL molecules are introduced into the MOF. − On the other hand, the liquid state and low vapor pressure of the IL molecules facilitate their confinement within the pores of the MOF. − The ionothermal synthesis and postsynthesis modification methods will be the two focus topics of this section.…”

Metal–organic frameworks (MOFs) and ionic liquids (ILs) represent promising materials for adsorption separation. ILs incorporated into MOF materials (denoted as IL/MOF composites) have been developed, and IL/MOF composites combine the advantages of MOFs and ILs to achieve enhanced performance in the adsorption-based separation of fluid mixtures. The designed different ILs are introduced into the various MOFs to tailor their functional properties, which affect the optimal adsorptive separation performance. In this Perspective, the rational fabrication of IL/MOF composites is presented, and their functional properties are demonstrated. This paper provides a critical overview of an emergent class of materials termed IL/MOF composites as well as the recent advances in the applications of IL/MOF composites as adsorbents or membranes in fluid separation. Furthermore, the applications of IL/MOF in adsorptive gas separations (CO2 capture from flue gas, natural gas purification, separation of acetylene and ethylene, indoor pollutants removal) and liquid separations (separation of bioactive components, organic-contaminant removal, adsorptive desulfurization, radionuclide removal) are discussed. Finally, the existing challenges of IL/MOF are highlighted, and an appropriate design strategy direction for the effective exploration of new IL/MOF adsorptive materials is proposed.

“…These cracks are lethal for the correct performance of the battery. To achieve improved flexibility, some authors have opted for the preparation of membranes in which the IL@MOF composite is incorporated into a polymer, giving rise to a solid polymer electrolyte (SPE) ( Guo, Song and Wang, 2019 ; Barbosa et al, 2021 ). This approach makes it possible to overcome the different issues faced by current solid polymer electrolytes, such as low ionic conductivity, or defective electrode-electrolyte interfaces.…”

This review focuses on the combination of metal-organic frameworks (MOFs) and ionic liquids (ILs) to obtain composite materials to be used as solid electrolytes in metal-ion battery applications. Benefiting from the controllable chemical composition, tunable pore structure and surface functionality, MOFs offer great opportunities for synthesizing high-performance electrolytes. Moreover, the encapsulation of ILs into porous materials can provide environmentally benign solid-state electrolytes for electrochemical devices. Due to the versatility of MOF-based materials, in this review we also explore their use as anodes and cathodes in Li- and Na-ion batteries. Finally, solid IL@MOF electrolytes and their implementation into Li and Na batteries have been analyzed, as well as the design and advanced manufacturing of solid IL@MOF electrolytes embedded on polymeric matrices.
