Although lithium-ion batteries are emerging as one of the leading energy storage technologies due to their high density, specific capacity, and fast charging speed, major challenges remain regarding use liquid electrolytes. These electrolytes directly affect safety durability batteries. While alternative materials such rigid solid-state have been developed improve safety, they often suffer from poor ionic conductivity inadequate interfacial contact with electrodes. issues hinder production widespread application To overcome these disadvantages, quasi-solid-state electrolytes, which include both solid components, extensively researched. Among these, metal-organic frameworks (MOFs) diverse morphological designs porous structures considered promising for fabrication high-performance This review summarizes recent research on MOF-based separators lithium metal batteries, including native MOFs, MOF composites, derivatives. The processes mechanisms enhancing electrochemical performance each separator material discussed. Furthermore, prospects this provided.

Benzoquinone (BQ) is considered a promising cathode material for aqueous zinc-ion batteries due to its simplest molecular structure and highest theoretical specific capacity among quinones. However, intrinsic problems derived from BQ including severe dissolution, narrow crystal interplanar d-spacings accessible by desolved Zn2+ only, poor conductivity cause inferior battery performance. Herein, strategy based on "nanopore-confined dual-site synergy mechanism" proposed stabilize the boost desolvation/coordination reactions stable fast Zn storage, which realized construction of CoS2 nanodot-embedded MOF-derived porous carbon (MPC) as an efficient host molecules. The MPC provides enough pore space accommodate substantial amount molecules with good electric conductivity, whereas in pores offering abundant Co S sites exerts strong chemical binding over species facilitates desolvation/coordination, respectively, synergistically suppressing dissolution cathodes imparting rapid reaction kinetics batteries. Consequently, developed BQ@CoS2-MPC delivers high reversible 458 mA h g-1 at 0.5 C, excellent rate capability, pronounced cycling stability low decay 0.003% per cycle 10,000 cycles 20 C. work proposes effective toward high-performance organic electrode materials.
