Zn metal, as one of the most promising anode materials for aqueous batteries, suffers from uncontrollable dendrite growth and water-induced parasitic reactions, which drastically compromise its cycle life Coulombic efficiency (CE). Herein, a nonionic amphipathic additive Tween-20 (TW20) is proposed that bears both zincophilic hydrophobic units. The segment TW20 preferentially adsorbs on anode, while exposed electrolyte side, forming an electrolyte-facing layer shields active water molecules. Moreover, theoretical calculation experimental results reveal can induce preferential (002) plane by adsorbing other facets, enabling dendrite-free anodes. Benefitting these advantages, stability reversibility anodes are substantially improved, reflected stable cycling over 2500 h at 1.0 mA cm

Rechargeable aqueous zinc-ion batteries (AZIBs) have been highly desired due to their low cost, intrinsic safety, environmental friendliness, and great potential in large-scale power storage systems. However, practical applications are impeded by unstable long-term electrochemical performances induced microstructure degradation of the cathode material, hydrogen evolution reaction electrolyte, dendritic growth on zinc anode upon cycling. In this work, rubidium cations (Rb

Abstract The poor anode/electrolyte interface triggered by abysmal dendritic growth and hydrogen evolution reactions (HER) hinders the development of aqueous zinc‐ion batteries (AZIBs). Here, a highly efficient electrolyte is formulated with sucralose (Sucral) additive to refresh solvated structure steer interfacial renovation, for building electronegative Cl‐modulated trinity effect in bulk‐interface between electrode. Experiment results theoretical studies jointly reveal that Sucral zincophilic hydrophilic hydroxyl groups can remodel primary Zn 2+ solvation shell interrupt strong H‐bond network from H 2 O molecules, thus boosting fast de‐solvation restricting undesirable HER. Simultaneously, three chlorides adsorbed possessing hydrophobic features enable O‐poor electric double‐layer (EDL), remodeling surface against corrosion. Additionally, it realizes preferential exposure (002) plane helping uniform deposition. synergy above factors achieves prolonged lifespan 3000 h (1.0 mA cm −2 , 1.0 mAh ), much better than Sucrose (Suc) electrolyte. Zn//V 5 full cell at A g −1 also maintains enhanced stability 1500 cycles 160 .

The main bottlenecks that hinder the performance of rechargeable zinc electrochemical cells are their limited cycle lifetime and energy density. To overcome these limitations, this work studied mechanism a dual-ion Zn-Cu electrolyte to suppress dendritic formation extend device life while concurrently enhancing utilization ratio thereby increasing density ion capacitors (ZICs). ZICs achieved best-in-class 41 watt hour per kilogram with negative-to-positive (n/p) electrode capacity 3.10. At n/p 5.93, showed remarkable 22,000 full charge-discharge cycles, which was equivalent 557 hours discharge. cumulative reached ~581 ampere gram, surpassing benchmarks lithium sodium highlighting promise for delivering high-performance, low-maintenance supplies.

Abstract The electric double layer (EDL) at the electrode/electrolyte interface plays a crucial role to electrochemical reactions of zinc ion batteries. For Zn anode, EDL consists H 2 O dipoles, which can cause corrosion and passivation. Herein, localized electronic‐rich (LER) structure performing as soild electrolyte interphase (SEI) changes electron distribution, leading rapid capture 2+ , thus promoting desolvation cH shell. Moreover, LER generates an electrostatic repulsion effect SO 4 2− . Consequently, unique O‐poor is reconstructed with distribution ‐H O‐SO inhibits side improves deposition kinetics In situ Raman intuitively confirms that zinc‐ion‐flux uniform during whole electroplating process. regulator for structure, leads smooth fast deposition. performance enhancement demonstrated by LER@Zn//LER@Zn cells, exhibit exceptional lifespan 4800 h. Furthermore, LER@Zn///MnO cell shows improved cycling stability over 1500 cycles, high capacity 124 mAh g −1 5 C.
