Abstract Commercialization of high energy density Lithium‐Sulfur (Li‐S) batteries is impeded by challenges such as polysulfide shuttling, sluggish reaction kinetics, and limited Li + transport. Herein, a jigsaw‐inspired catalyst design strategy that involves in situ assembly coherent nano‐heterocrystal ensembles (CNEs) to stabilize high‐activity crystal facets, enhance electron delocalization, reduce associated barriers proposed. On the surface, stabilized facets induce aggregation. Simultaneously, surrounded surface with enhanced activity promote 2 S deposition diffusion, synergistically facilitating continuous efficient sulfur redox. Experimental DFT computations results reveal dual‐component hetero‐facet alters coordination Nb atoms, enabling redistribution 3D orbital electrons at center promoting d‐p hybridization sulfur. The CNE, based on level gradient lattice matching, endows maximum transfer catalysts establishes smooth pathways for ion diffusion. Encouragingly, NbN‐NbC‐based pouch battery delivers Weight 357 Wh kg −1 , thereby demonstrating practical application value CNEs. This work unveils novel paradigm designing high‐performance catalysts, which has potential shape future research electrocatalysts storage applications.

Abstract Lithium–sulfur (Li–S) batteries suffer from severe polysulfide shuttle, retarded sulfur conversion kinetics and notorious lithium dendrites, which has curtailed the discharge capacity, cycling lifespan safety. Engineered catalysts act as a feasible strategy to synchronously manipulate evolution behaviors of species. Herein, chlorine bridge‐enabled binuclear copper complex (Cu‐2‐T) is in situ synthesized electrolyte homogeneous catalyst for rationalizing Li–S redox reactions. The well‐designed Cu‐2‐T provides completely active sites sufficient contact homogeneously guiding Li 2 S nucleation/decomposition reactions, stabilizing working interface according synchrotron radiation X‐ray 3D nano‐computed tomography, small angle neutron scattering COMSOL results. Moreover, with content 0.25 wt% approaching saturated concentration further boosts optimization function really operated batteries. Accordingly, capacity retention battery elevated 51.4% 86.3% at 0.2 C, reaches 77.0% 1.0 C over 400 cycles. Furthermore, cathode assistance realizes stable under practical scenarios soft‐packaged pouch cell high loading (6.5 mg cm −2 usage 4.5 µL −1 ).

Abstract Lithium‐sulfur batteries (LiSBs) with high energy density still face challenges on sluggish conversion kinetics, severe shuttle effects of lithium polysulfides (LiPSs), and low blocking feature ordinary separators to LiPSs. To tackle these, a novel double‐layer strategy functionalize is proposed, which consists Co atomically dispersed CoN 4 decorated Ketjen black (Co/CoN @KB) layer an ultrathin 2D Ti 3 C 2 T x MXene layer. The theoretical calculations experimental results jointly demonstrate metallic sites provide efficient adsorption catalytic capability for long‐chain LiPSs, while active facilitate the absorption short‐chain LiPSs promote Li S. stacking serves as microscopic barrier further physically block chemically anchor leaked from pores gaps Co/CoN @KB layer, thus preserving within anchoring‐conversion reaction interfaces balance accumulation “dead S” Consequently, ultralight loading @KB‐MXene, LiSBs exhibit amazing electrochemical performance even under sulfur lean electrolyte, outperforming lithium‐selenium (LiSeBs) can also be achieved. This work exploits universal effective functionalized separator regulate equilibrium adsorption‐catalytic interface, enabling high‐energy long‐cycle LiSBs/LiSeBs.

Lithium metal batteries (LMBs) offer significant advantages in energy density and output voltage, but they are severely limited by uncontrollable Li dendrite formation resulting from uneven Li+ behaviors high reactivity with potential co-solvent plating. Herein, to uniformly enhance the desolvation diffusion, local solvation shell structure is optimized constructing an anion-braking separator, hence dynamically reducing self-amplifying behavior of dendrites. As a prototypal, two-dimensional lithiated-montmorillonite (LiMMT) blade-coated on commercial where abundant −OH groups as Lewis acidic sites electron acceptors could selectively adsorb corresponding FSI– anions, regulating restricting their migration. Meanwhile, weakened anion mobility delays time breaking electrical neutrality, nucleation quantified through respective experimental, theoretical spectroscopical results, providing comprehensive understanding modifying cation dendritic growth suppression. anticipated, long plating/stripping lifespan up 1800 h significantly increased average Coulombic efficiency 98.8% achieved under 3.0 mAh cm–2. The fabricated high-loading Li-LFP or Li-NCM523 full-cells display cycle durability enhanced capacity retention nearly 100%, instructive guide towards realizing dendrite-free LMBs.
