Abstract Engineering atom-scale sites are crucial to the mitigation of polysulfide shuttle, promotion sulfur redox, and regulation lithium deposition in lithium–sulfur batteries. Herein, a homonuclear copper dual-atom catalyst with proximal distance 3.5 Å is developed for batteries, wherein two adjacent atoms linked by pair symmetrical chlorine bridge bonds. Benefiting from their unique coordination, increased active interface concentration synchronously guide evolutions species. Such delicate design breaks through activity limitation mononuclear metal center represents concept battery realm. Therefore, remarkable areal capacity 7.8 mA h cm −2 achieved under scenario content 60 wt. %, mass loading 7.7 mg electrolyte dosage 4.8 μL −1 .

Abstract Chalcogenide cathodes with multi‐electron transfer characteristics are indispensable to aluminum‐ion batteries (AIBs). Nevertheless, their grievous capacity degradation and sluggish reaction kinetics remain fundamental challenges for the practical application. Herein, a Cu 2 S/Ni 3 S multiphase structure within metal‐organic frame (MOF) derived carbon decoration layer (CNS@MC) is constructed elevate intrinsic electronic properties of chalcogenide cathode realize high‐performance AIBs. The existence outer strong orbital interaction at inner heterointerfaces eliminates bandgap arises more electrons Fermi level, efficiently reducing energy barrier electron achieving high reactivity cathodes. CNS@MC also presents active solvent groups, which beneficial capture Al 3+ facilitate three‐electron charge‐storage reactions. Experimental results demonstrate that tailored possesses superior redox due sufficient surface area rapid Al‐ion diffusion during cycling. Meanwhile, robust delivers ultra‐high electrochemical stability (131.1 mAh g −1 over 3500 cycles) coulombic efficiency outstanding rate performance. This work offers new opportunities optimizing electrodes based on MOF derivatives heterostructure, providing novel thoughts designing

The long-term stability of Li–S batteries is significantly compromised by the shuttle effect and insulating nature active substance S, constraining their commercialization. Developing efficient catalysts to mitigate lithium polysulfides (LiPSs) still a challenge. Herein, we designed synthesized rose-like cobalt–nickel bimetallic oxide catalyst NiCo2O4–OV enriched with oxygen vacancies (OV) verified controllable synthesis different contents OV. Introducing OV proved be an approach for controlling electronic structure electrocatalyst managing absorption/desorption processes on reactant surface, thereby addressing challenges posed LiPS sluggish transformation kinetics in batteries. In addition, investigated NiCo2O4 adsorption capacity LiPSs using experiments density functional theory (DFT) simulations. With increase level OV, binding energy between two enhanced, more obvious. contributes decomposition Li2S diffusion Li+ batteries, which promotes kinetic process
