Metal−Organic Frameworks for High‐Energy Lithium Batteries with Enhanced Safety: Recent Progress and Future Perspectives

Abstract

frameworks (MOFs) are a relatively new class of crystalline, highly-porous organic-inorganic hybrid materials that have been attracting increasing attention in the field of high-energy lithium batteries. In this review, recent achievements are detailed regarding the innovative design and processing of pristine MOFs and their nanocomposites for lithiumÀsulfur and lithiumÀoxygen batteries with high specific energy. Furthermore, the benefits and challenges associated with the applications of MOF-based materials in solid-state lithium-metal batteries are discussed. Lastly, future prospects for the rational design and manufacturing of MOF-based materials are provided.can also be used as Li-ion conductors for all-solid-state electrolytes, wherein Li + ions can be fast mobilized along open metal sites. [12d,16] There are several good review articles addressing MOFderived materials (e. g., porous carbon or metal oxides) for energy storage applications, [10,17] which are not covered in detail in this review. Here, a comprehensive overview is provided that focuses on recent advancement in pristine MOFs and their nanocomposites for emerging high-energy Li batteries (LiÀS, LiÀO 2 , and solid-state Li-metal batteries). Furthermore, the advantages and challenges associated with the development of MOF-based materials are discussed. Lastly, the future prospects for the rational design and manufacturing of MOF-based materials are outlined. 2 3 4 5 6 7 8

Integrating Conductivity, Captivity, and Immobility Ability into N/O Dual‐Doped Porous Carbon Nanocage Anchored with CNT as an Effective Se Host for Advanced K‐Se Battery

“…[18a,19b,20] It could be expected that the encapsulation of Se into the hollow cavities of MOF-derived hollow carbon materials will effectively constrain Se or polyselenide, and also ensure the fast diffusion of both ions and electrons. [21] Li et al reported MOFderived nitrogen-doped core-shell hierarchical porous carbon for the encapsulation of Se, which performed well in Li-Se batteries. [22] Kang et al developed bimodal porous carbon nanofibers that possessed unique pore structures by carbonization of PAN/ZIF-8 nanofibers, which boosted the utilization rate of the Se cathode.…”

Tunable Interaction between Metal‐Organic Frameworks and Electroactive Components in Lithium–Sulfur Batteries: Status and Perspectives

“…As shown in Figure 4b [21] Moreover, organic linkers are multitopic organic ligands containing N-donors or O-donors, such as, 2-methylimidazole, 1, 4-benzenedicarboxylate, 1, 3, 5-benzenetricarboxylate, etc. [25] These SBUs and ligands can be joined by directional coordination bonds to build different topology nets via coordination-driven self-assembly. As a result, the formed pore shape range from cage-like, cube-like, cylinderlike shape.…”

Conversion of a microwave synthesized alkali-metal MOF to a carbonaceous anode for Li-ion batteries

“…As a rapidly emerging class of higher dimensional crystalline materials, metal-organic frameworks (MOFs) and their derivatives or composites have exhibited potential as functional materials for an array of electrochemical applications. [13][14][15][16][17][18] The structural features of MOFs are carried further into their derivatives, making MOFs attractive self-sacricial agents to cater for the demands of the desired electrochemical characteristics. [19][20][21][22][23][24][25][26] Typically, MOF-derived carbons are prepared by the energy intensive process of pyrolysis at high temperatures under inert conditions.…”
