The unstable Zn interface caused by undesired dendrites and parasitic side reactions greatly impedes the deployment of aqueous metal batteries. Herein, an efficient adsorptive additive strategy is proposed to reshape electric double layer regulate interfacial chemistry. 2-Hydroxy-4′-(2-hydroxyethoxy)-2-methylpropiophenone (Irgacure 2959) was selected owing its strong adsorption ability, intermolecular hydrogen bonding, exposed electronegative carbonyl group. constructed self-adaptive adlayer contributes a localized H2O, SO42–-poor environment horizontal alignment deposits along (002) plane, thus endowing thermodynamically stable highly reversible electrochemistry. As result, plating/stripping 3800 h high Coulombic efficiency 99.8% are achieved. Intriguingly for practical application, economical (0.016 USD L–1) enables discharge output 500 cycles in Zn/VS2 cells at low negative-to-positive capacity ratio 2.5 (cathode mass loading: 10.8 mg cm–2), holding great promise use scalable, low-cost, rechargeable battery.

Abstract Proton insertion chemistry in aqueous zinc‐ion batteries (AZIBs) is becoming a research hotspot owing to its fast kinetics and additional capacities. However, H + storage mechanism has not been deciphered the popular MoS 2 ‐based AZIBs. Herein, we innovatively prepared /poly(3,4‐ethylenedioxythiophene) (MoS /PEDOT) hybrid, where intercalated PEDOT only increases interlayer spacing (from 0.62 1.29 nm) electronic conductivity of , but also activates proton chemistry. Thus, highly efficient reversible /Zn 2+ co‐insertion/extraction behaviors are demonstrated for first time Zn‐MoS batteries. More intriguingly, co‐inserted protons can act as lubricants effectively shield electrostatic interactions between /PEDOT host divalent Zn enabling accelerated ion‐diffusion exceptional rate performance. This work proposes new concept “proton lubricant” driving transport broadens horizons

Tunnel-type vanadium oxides are promising cathodes for aqueous zinc ion batteries. However, unlike layer-type with adjustable layer distances, enhancing ion-transport kinetics in tunnels characterized by fixed sizes poses a considerable challenge. This study highlights that the macroscopic arrangement of electrode crucially determines tunnel orientation, thereby influencing transport.
