The sustained water consumption and uncontrollable dendrite growth strongly hamper the practical applications of rechargeable zinc (Zn) metal batteries (ZMBs). Herein, for first time, we demonstrate that trace amount chelate ligand additive can serve as a "molecular sieve-like" interfacial barrier achieve highly efficient Zn plating/stripping. As verified by theoretical modeling experimental investigations, benzenesulfonic acid groups on molecular not only facilitates its solubility selective adsorption anode, but also effectively accelerates de-solvation kinetics Zn2+ . Meanwhile, central porphyrin ring expels free molecules from via chemical binding against hydrogen evolution, reversibly releases captured to endow dendrite-free deposition. By virtue this non-consumable additive, high average plating/stripping efficiency 99.7 % over 2100 cycles together with extended lifespan suppressed decomposition in Zn||MnO2 full battery were achieved, thus opening new avenue developing durable ZMBs.

Uncontrolled growth of Zn dendrites hinders the future development aqueous Zn-ion batteries. Despite that (100) plane possesses better zincophilic ability and fast kinetics, are generally suppressed via (002) plane-oriented deposition in previous reports; ordered plane-dominant deposition, especially under high current density has not yet been realized. Herein, vertically-oriented plating with preferential is reported using disodium lauryl phosphate (DLP) as an electrolyte additive. DLP preferentially anchored on crystal polar group, then atoms retarded by long alkyl chain, finally promoting preferred plane. This unique pattern results ultrastable plating/stripping at a super-high 50 mA cm

Abstract Aqueous zinc ion batteries are promising candidates for large‐scale energy storage. Nonetheless, the stability of Zn anodes in aqueous electrolytes is compromised by dendritic growth and undesirable side reactions. In this article, citrulline (Cit), a biocompatible compound, investigated as an electrolyte additive to achieve superior anodes. Experimental results theoretical calculations demonstrate that Cit, serving bifunctional additive, possesses abundant highly polar groups (─NH 2 ─COOH) facilitate strong interactions with 2+ metal. This dual regulation solvation shell electrical double layer at anode/electrolyte interface effectively mitigates dendrite suppresses reactions, resulting exceptional anode. Consequently, Zn||Zn symmetric incorporating Cit exhibit stable operation over 1600 h 1.0 mA cm −2 mAh , maintain cycling 650 even under demanding conditions 10.0 corresponding ultra‐high cumulative plated capacity 3.25 Ah . Furthermore, Zn||Cu asymmetric remarkable Coulombic efficiency 99.6% 0.5 These advancements also extend improved performance assembled full batteries.

Rampant dendrite formation and serious adverse parasitic reactions induced by migration of dissolved V/Mn cathode ions on Zn anode have hampered the high performance aqueous zinc-ion batteries (AZIBs). Inspired coordination chemistry between functional groups polymer electrolyte ions, a freestanding layer consisting dopamine-functionalized polypyrrole (DA-PPy) nanowires served as selective ion transport at anode–electrolyte interface to address these two issues, which could simultaneously avoid polarization caused introduction an additional interface. On one hand, DA-PPy displays excellent zinc charge transfer ability, well provides chemical homochanneling for interface, endow with properties guider physical barrier inhibition. other can trap excess transition metal fleeing from cathodes, thus serving barrier, preventing Vx+/Mnx+-passivation surface anode. Consequently, AZIBs based V2O5 MnO2 cathodes involving show great improvement in capacity retention.
