Summary: This article discusses the significant gap between academic research and industrial market needs in the field of lithium-based batteries, which is partly due to the lack of peer-reviewed publications from industry. The authors present a non-academic perspective to bridge the divide, focusing on key metrics and challenges for developing practical batteries. They emphasize the need to consider various performance aspects together when developing new technologies and also examine the suitability of supply chains, sustainability of materials, and the impact on system-level cost as important factors.

Summary: Understanding sulfur conversion chemistry is crucial for the development of sulfur-based high-energy-density batteries. The relationship between the electronic structure of the catalyst and its activity remains unclear. In this study, we establish a direct correlation between the p electron gain of S in p-block metal sulfides and the apparent activation energies (E-a) for the SRR, specifically the Li2Sn to Li2S conversion. The highest p charge is observed in bismuth sulfide, resulting in the lowest E-a and a high SRR rate.

Summary: A novel type of ZnCo-based metal-organic framework nanoboxes (ZnCo-MOF NBs) were designed and prepared as a functional sulfur host for Li-S batteries. The hollow architecture of ZnCo-MOF NBs ensures fast charge transfer, improved sulfur utilization, and effective confinement of lithium polysulfides (LiPSs). The atomically dispersed Co-O-4 sites in ZnCo-MOF NBs capture LiPSs and accelerate their conversion kinetics electrocatalytically.

Summary: A catalytic two-dimensional heterostructure composite (OMC-g-MXene) with evenly grafted mesoporous carbon on MXene nanosheets is prepared as interfacial kinetic accelerators in Li-S batteries. The grafted mesoporous carbon prevents nanosheet stacking and accelerates ion diffusion, while the exposed defect-rich OMC-g-MXene inhibits polysulfide shuttling and enhances electrochemical conversion kinetics and efficiency. The cells with OMC-g-MXene exhibit high capacity, superior rate performance, and low decay rate, demonstrating promising practical applications.

Summary: Constructing high performance electrocatalysts, such as the single atomic catalyst of Fe-N-4 moiety doping periphery with S (Fe-NSC), can effectively enhance lithium polysulfides (LiPSs) adsorption and facilitate sulfur conversion, improving the energy density and cycle life of rechargeable lithium-sulfur (Li-S) batteries. By modifying the graphene oxide supported Fe-NSC catalyst (Fe-NSC@GO) to the commercial separator, Li-S cells exhibit high discharge capacity and excellent cyclability, with 1156 mAh g(-1) at 1 C rate and a low capacity decay of only 0.022% per cycle over 1000 cycles. This work provides new insights into structural tuning of electrocatalysts to improve the electrochemical performance of Li-S batteries.

Summary: Lithium-sulfur batteries are highly promising successors to lithium-ion batteries due to their high energy density, low cost, and environmental friendliness. However, their practical applications are hindered by slow sulfur redox kinetics and the polysulfide shuttle effect. The use of metal-organic frameworks (MOFs) as catalysts to improve the electrochemical performance of lithium-sulfur batteries has attracted significant research interest.

Summary: In this study, a novel three-dimensional hollow microsphere hierarchical structure of nickel-zinc MOFs (NZMF/CF) was successfully fabricated on carbon fabric as a binder-free electrode for supercapacitor applications. The NZMF/CF electrode showed higher rate capacity and specific capacitance compared to NZMF, leading to a superior energy density and cyclic stability in a split cell asymmetric supercapacitor device (SC-ASD). This research provides a versatile scheme for efficiently preparing MOF-based binder-free energy storage materials for future hybrid and flexible electronic devices.

Summary: In this study, a porous carbon nanofiber with an oxygen-dominated Ti3C2 MXene nanosheet (O-Ti3C2@CNF) was designed and synthesized as an all-purpose interlayer for lithium-sulfur (Li-S) batteries. By controllable surface modifications and oxygen regulation, the O-Ti3C2@CNF exhibited strong physical/chemical affinity and fast reaction kinetics towards sulfur species. The interlayer enabled high-flux lithium diffusion and dendrite-free lithium anode. A practical, flexible Li-S pouch battery with excellent areal capacity was assembled using the symmetric interlayer design.

Summary: A new type of single-atomic iron mediator with a designed FeN3P1 coordination structure is reported to boost bidirectional polysulfide conversion. The substitution by one P atom at the first-coordination shell of Fe center is found to strengthen adsorption toward sulfur species and reduce energy barrier for Li2S decomposition. The bidirectional electrocatalytic behavior for polysulfide conversion via FeN3P1 mediator is confirmed by electrokinetic analysis. This strategy offers an example in probing the correlation between the definitive structure of single atoms and their catalytic performance in Li-S chemistry.

Summary: This study investigates a catalyst for high-performance lithium-sulfur batteries. By designing a cobalt-decorated N-doped hollow carbon nanofiber catalyst, the electron redistribution resulting from long-range interactions enhances the generation of oxygen radicals and the dissociation of hydrogen sulfide, enabling selective oxidation of hydrogen sulfide. Furthermore, the hollow structure of the catalyst provides ample storage space for rapid gas diffusion and allows for the in-situ fabrication of high sulfur-loading carbon-based cathodes during the oxidation of hydrogen sulfide. This chemical reaction-induced deposition results in a more uniform distribution of solid sulfur upon carbon than traditional methods, leading to superior electrochemical performance in lithium-sulfur batteries.

Summary: Zeolitic imidazolate frameworks (ZIFs) undergo pressure-induced phase transitions that are peculiar to each ZIF, and the metal dependence of the ambient pressure and high pressure phases of ZIF-8(M) with Mg, Fe, and Zn has been studied. The substitution of Zn with Mg or Fe influences the gate opening energy significantly, with ZIF-8(Fe) showing a different lowest energy phase structure compared to ZIF-8(Mg) and ZIF-8(Zn), which is closer to the high pressure phase. Additionally, ZIF-8(Fe) is confirmed to have high-spin divalent iron in antiferromagnetic coupling, making it a promising material for catalysis and photocatalysis due to its band gap in the visible light range.
