“…Considering the above‐mentioned criteria with respect to oxygen cathode materials, highly porous MOFs with a large number of accessible active sites qualify for the application as effective cathode catalysts that enable the fast diffusion of active species in Li−O 2 batteries, although their relatively low electrical conductivity needs to be improved. Indeed, MOFs have received much attention for oxygen cathodes in Li−O 2 batteries, as summarized in Table S2a …”

“…As discussed in Section 2, the hybridization of MOFs with carbon materials leads to MOF/carbon hybrids with enhanced electrical conductivity . Very recently, our group prepared M‐MOF‐74@CNT hybrids (M=Mn and Zn) via an additive‐mediated method (Figure a) as cathode materials for the operation of Li−O 2 batteries in humid oxygen . Compared to pure MOF nanoparticles, the M‐MOF‐74@CNT hybrids showed a mitigated agglomeration of MOF particles and a highly porous structure due in part to the interwoven CNTs (Figure b and c), which results in the fast diffusion kinetics of active species.…”

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).

“…Therefore, solid catalysts for LOBs must be designed to catalyze the formation and decomposition of LiOH, which have been demonstrated with the nanoparticles (NPs) of Ru/γ-MnO 2 [21], Mn-metal-organic framework-74@carbon nanotubes (Mn-MOF-74@CNTs) [22] and Co 3 O 4 [20]. Mn-based catalysts are widely applied in LOBs because of their advantages, such as low cost and good intrinsic catalytic activity [23][24][25][26], regardless if the discharge product is Li 2 O 2 or LiOH.…”

The low energy efficiency and poor cycle stability arising from the high aggressivity of discharge products toward organic electrolytes limit the practical applications of Li-O 2 batteries (LOBs). Compared with the typical discharge product Li 2 O 2 , LiOH shows better chemical and electrochemical stability. In this study, a free-standing cathode composed of hydrangea-like δ-MnO 2 with Ag nanoparticles (NPs) embedded in carbon paper (CP) (Ag/δ-MnO 2 @CP) is fabricated and used as the catalyst for the reversible formation and decomposition of LiOH. The possible discharge mechanism is investigated by in situ Raman measurement and density functional theory calculation. Results confirm that δ-MnO 2 dominantly catalyzes the conversion reaction of discharge intermediate LiO 2* to LiOH and that Ag particles promote its catalytic ability. In the presence of Ag/δ-MnO 2 @ CP cathode, the LOB exhibits enhanced specific capacity and a high discharge voltage plateau under humid O 2 atmosphere. At a current density of 200 mA g −1 , the LOB with the Ag/δ-MnO 2 @CP cathode presents an overpotential of 0.5 V and an ultra-long cycle life of 867 cycles with a limited specific capacity of 500 mA h g −1 . This work provides a fresh view on the role of solid catalysts in LOBs and promotes the development of LOBs based on LiOH discharge product for practical applications.

“…Considering most MOFs possess low electrical conductivity, it is desired to develop strategies to improve the conductivity of MOFs, such as hybridization with conductive matrix and functionalization with guest molecules. Mn-MOF-74 nanoparticles were directly grown on 1D CNTs by a simple additive-mediated synthesis as cathode materials for Li-O 2 batteries [84]. The Mn-MOF-74@CNTs could provide conductive networks and prevent the agglomeration of MOF nanoparticles, thus exhibiting fewer side reactions and improved cycling performance in a humid oxygen environment.…”
