ABSTRACT The limited energy density of the current Li‐ion batteries restricts electrification transportation to small‐ and medium‐scale vehicles. On contrary, Li‐O 2 (LOBs), with their significantly higher theoretical density, can power heavy‐duty transportation, if sluggish electrode kinetics in these devices be substantially improved. use solid electrocatalysts at cathode is a viable strategy address this challenge, but fail provide sufficient discharge depths cyclability, primarily due formation film‐like product, Li₂O₂, on catalytic sites, which obstructs charge transport gas diffusion pathways. Here, we report that triphase heterogeneous catalyst comprising NiCoP, NiCo S 4 , O assembled into hierarchical hollow architecture (NC‐3@Ni), efficiently modulates morphology orientation facilitating sheet‐like growth Li perpendicular surface. These modifications enable LOB deliver high capacity 25 162 mAh g −1 400 mA along impressive cycling performance, achieving 270 cycles depth 1000 exceeding 1350 h continuous operation. This promising performance attributed presence individual electrophilic nucleophilic phases within microstructure catalyst, collectively promoting . image

Abstract Potassium‐based batteries, including potassium‐ion (PIBs) and potassium metal batteries (PMBs), are gaining attention as alternatives to lithium‐ion (LIBs). However, potassium's large ionic radius (1.38 Å) reduces charge density, weakens solvation, increases energy barriers for K + diffusion, leading slower reaction kinetics, thicker solid electrolyte interphase (SEI) layers, dendrite formation. To address these challenges, a novel single‐atom Fe‐N 4 dipole–dipole coupling (SA.Fe) is proposed. The unique coordination highly conductive Ketjen black (KB) substrate establish rapid horizontal electron transfer network, enhancing electrode interface reactions. Moreover, Fe‐N‐C generates short‐range polar electric field, improving affinity diffusion. This coherent effectively regulates migration, significantly kinetics lowering diffusion barriers. SA.Fe anode delivers high reversible capacities (446.3 mAh g −1 ) exceptional durability (10 000 cycles at 2.0 A in PIBs, alongside remarkable stability (600 0.5 mA cm −2 fast (K metal) deposition without formation PMBs. study highlights the potential of dipole efficient storage dendrite‐free offering promising pathway next‐generation potassium‐based systems.

Abstract Upcycling of high‐value metals (M = Ni, Co, Mn) from spent ternary lithium‐ion batteries to the field lithium‐oxygen is highly appealing, yet remains a huge challenge. In particular, alloying recovered M components with Pt and applied as cathode catalysts have not been reported. Herein, fresh L1 2 ‐type 3 medium‐entropy intermetallic nanoparticle first proposed, confined on N‐doped carbon matrix (L1 ‐Pt (Ni 1/3 Co Mn )@N‐C) based 111 typed LiNi 1‐x‐y x y O cathode. This well‐defined catalyst combines both features long‐range order face‐centered cubic structure short‐range disorder in sites. The former contributes enhancing structural stability, latter further facilitates deeply activating catalytic activity Experiments theoretical results demonstrate that local coordination environment electronic distribution are fundamentally modulated via surrounding disordered atoms, which greatly optimize affinity toward oxygen‐containing intermediates facilitate deposition/decomposition kinetics thin‐film Li discharge products. Specifically, 1/3) @N‐C exhibits an ultra‐low overpotential 0.48 V achieves 220 cycles at 400 mA g −1 under 1000 mAh . work provides important insights for recycling into advanced catalyst‐related applications.
