Summary: We report Mo-Ni bimetal sulfide nanosheets with dense heterointerfaces and defects as a catalyst for the multi-step transformation of lithium polysulfide intermediates. The MoS2 in the catalyst is effective in catalyzing the phase transformation from Li2S8 to Li2S4, while NiS2 enhances the conversion from Li2S4 to Li2S and the dissociation of Li2S. This integrated system selectively promotes the stepwise conversion of sulfur and improves battery performance.

Summary: Lithium-sulfur (Li-S) batteries are promising as new-generation energy storage systems due to their high energy density, cost-effectiveness, and eco-friendliness. However, soluble lithium polysulfides (LiPSs) and dendrite growth of metallic Li hinder their practical applications. This review provides a comprehensive summary of strategies for simultaneously inhibiting shuttle behavior and dendrite growth, including the use of host materials for Li-S full cell, modified functional separators, and tailored electrolytes. The review also discusses the Li-S chemistry mechanism, catalyst principles, and advanced characterization technologies.

Summary: The mechanism of multifunctional sulfur-fixing materials is crucial for the design of effective electrocatalysts for lithium-sulfur batteries (LSBs). Metal coordination compounds (M = Co / Fe / CoFe) are chosen as cathode additives to promote reaction kinetics and focus on adsorption-catalysis mechanism. The combination of Co and Fe sites inhibits polysulfides diffusion and induces rapid deposition of lithium sulfide, resulting in excellent cyclability and capacity retention for LSBs.

Summary: Lithium-sulfur (Li-S) batteries have potential as next-generation energy storage systems, but their practical applications are hindered by slow kinetics and shuttle effects of polysulfides. This study introduces a Co/CoSe junction as an efficient catalyst for polysulfide conversion, due to its metallic electron mobility and field-enhanced catalytic activity. The junction's charge distribution rearrangement and strong interaction with polysulfides, along with the durability provided by CoSe, contribute to its high catalytic activity and long-term performance. This Co/CoSe junction offers an alternative approach for enhancing the catalytic conversion of polysulfides.

Summary: A wide range of nickel-based catalysts have been studied for the oxygen evolution reaction (OER) in alkaline media, but their activity and Tafel slope values vary greatly. To understand this variation, we investigated Ni80Fe20OOH catalysts with different loadings under various conditions. We found that the Tafel slope value of Ni80Fe20OOH is around 30 mV dec(-1) at low current density (<5 mA cm(-2)), but increases with higher polarization and is affected by rotation rate, loading, hydroxide concentration, and sonication. These Tafel slope values are influenced by non-kinetic effects such as bubbles, potential-dependent changes in ohmic resistance, and (internal) OH- gradients. It is recommended to plot Tafel slopes against current or potential to distinguish kinetic and non-kinetic effects.

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 1D pi-d conjugated metal-organic framework (MOF), Ni-MOF-1D, is presented as an efficient sulfur host to overcome the shuttling behavior and sluggish conversion kinetics of intermediate lithium polysulfides (LiPS) in lithium-sulfur batteries (LSBs). Ni-MOF-1D exhibits a remarkable binding strength to trap soluble LiPS species and acts as an effective catalyst for S reduction and Li2S oxidation. The delocalization of electrons in the pi-d system of Ni-MOF-1D provides superior electrical conductivity, leading to excellent performance in LSBs.
