Abstract The porous structure is critical for carbonaceous electrode‐based zinc‐ion capacitors (ZICs) to achieve excellent electrochemical performance, but the corresponding structure‐electrochemical performance relationship yet be fully understand. Herein, three types of N‐doped carbons with different structures are developed investigate between pore size distribution and devices. optimized carbon (LVCR) exhibits large surface area, plentiful oxygen functional groups, hierarchical that facilitates electron transfer ion diffusion. Consequently, LVCR‐based ZIC a remarkable peak power density 31.4 kW kg −1 an impressive specific energy 126.6 Wh . Moreover, it demonstrates exceptional longevity, retaining capacitance 97.7% even after undergoing 50 000 cycles. Systematic characterization macroporous mesoporous determine stages Zn 2+ storage kinetics. LVCR attributed fast transport channels provided by facilitated reversible chemisorption desorption. This work not only deepens understanding charge mechanism, also provides guidelines rationally designing materials toward high‐performance ZICs in view relationship.

Abstract In advancing aqueous zinc‐ion batteries (AZIBs) toward commercial viability, vanadium (V)‐based cathodes are pivotal, offering broad redox ranges, and compatibility with water's electrochemical limits. Despite their great potentials, V‐based face challenges in transitioning from lab to commercialization. Defect engineering is exploited as a pivotal technique that endows the unexpected physical chemical properties break intrinsic bottleneck and, turn, enhance performances. This review delves into role of defect on materials, underscoring its potential mitigating critical challenges. It starts by encapsulating current characteristics AZIBs. Research efforts related various defects, such oxygen vacancies, cation cationic doping, anionic water intercalation, lattice disorders/amorphization, then rationalized discussed. The fabrication characterization techniques also summarized. By integrating conclusions existing works tailoring strategies, few perspectives provided for systematically employing pave way more efficient transition these promising materials laboratory breakthroughs commercially viable energy storage solutions.

Abstract Aqueous zinc‐ion batteries have garnered significant attention due to their abundant materials, low production costs, and safety. However, these suffer from severe side reactions, which are closely associated with the presence of a substantial amount solvent at electrode surfaces. Herein, 1,4,7,10,13,16‐hexaoxacyclooctadecane (18‐crown‐6) is added electrolyte illustrate both theoretically experimentally its contribution rapid desolvation aspect. It shown that addition 18‐crown‐6 greatly facilitates solvated structure prevents collection molecules on surface zinc anode, thus inhibiting hydrogen precipitation reaction. also enhances transference number ions, makes interfacial electric field anode stable promotes orderly diffusion uniform nucleation Zn 2+ , inhibits growth dendrites. As result, containing as additives shows cycle life, Zn||Zn symmetric cell cycled for nearly 1700 h 1 mA cm −2 showing improvement in Coulombic efficiency.

Abstract The application of zinc‐ion batteries (ZIBs) is seriously challenged by the poor stability Zn anode and cathode in aqueous solution, which closely associated with electrolyte structure water reactivity. Herein, issues both for can be simultaneously addressed via tuning solvation hybrid tripropyl phosphate (TPP) as co‐solvent. On anode, a robust poly‐inorganic solid interphase (SEI) layer comprised 3 (PO 4 ) 2 ‐ZnS‐ZnF species situ formed, effectively suppressing parasitic reaction dendrite evolution. For V O 5 cathode, notorious vanadium dissolution restricted improved achieved. optimized facilitates reversible redox kinetics at anode. Consequently, Zn||Zn cells display extended cycling lifespans over 3000 h 1 mA cm −2 , mAh .

Abstract The crosstalk of transition metal ions between the oxide cathode and Zn anode restricts practical applications aqueous zinc‐ion batteries (ZIBs). Herein, we propose a decoupled electrolyte (DCE) consisting nonaqueous‐phase (N‐phase) anolyte an aqueous‐phase (A‐phase) catholyte to prevent Mn 2+ , thus extending lifespan MnO 2 ‐based ZIBs. Experimental measurements theoretical modelling verify that trimethyl phosphate (TMP) not only synergistically works with NH 4 Cl in N‐phase enable fast conduction while blocking diffusion toward anode, but also modifies solvation structure suppress dendrite formation corrosion on anode. Meanwhile, A‐phase effectively accelerates reaction kinetics. as‐developed Zn|DCE|MnO cell delivers 80.13 % capacity retention after 900 cycles at 0.5 A g −1 . This approach is applicable for other cathode‐based ZIBs, thereby opening new avenue developing ultrastable
