Alkaline zinc‐based batteries (AZBs) can yield higher operating voltages due to a more negative electrode potential of zinc metal in alkaline electrolytes compared with neutral electrolytes, delivering high energy density practical manufacturing applications. However, AZBs also exhibit pronounced problems severe corrosion the anode by strongly electrolyte environment. Combined reaction mechanism batteries, negatively charged carbon dots are innovatively used construct barrier both physical and chemical effects. Zinc exposure is reduced superior barrier, which assures transmission ions rather than zincate through electrostatic force balance, thus improving distribution electric field for ion deposition as well avoiding accumulation at interface. The number harmful dendrite formation was found be significantly suppressed situ optical microscopy. When coupled silver oxide cathode testing, assembled silver‐zinc battery results significant enhancement its cyclic life. It believed that this study will propel development provide new insights their application.

Excessive dendrite formation and side reactions compromise the reversibility stability of zinc anodes, obstructing deployment aqueous zinc-ion batteries. An economical, yet effective solution involves deploying electrolyte additives for a solid interphase (SEI) on metal anodes. Managing to fabricate an optimal SEI via these remains challenging. Here, we introduce cost-effective copper sulfate additive, enabling creation multifunctional copper–zinc alloy SEI. The SEI's superior electrical conductivity, zincophilic sites, ample free space, elevated surface energy facilitate homogeneous Zn nucleation deposition, thereby expediting electrochemical kinetics mitigates formation. Additionally, uniform suppresses corrosion hydrogen evolution reaction, augmenting deposition/dissolution reversibility. Consequently, Zn||Zn symmetric cells with additive exhibiting remarkable cycling over 5000 h at 0.5 mA cm–2, extraordinary average Coulombic efficiency 99.4% lifespan 1600 stable voltage hysteresis 2 cm–2 cm–2.

Despite showing low cost, inherent safety, and high suitability, the rechargeable Zn–I2 aqueous batteries are still seriously suffering from self-discharge energy density issues stemming I2 dissolution, polyiodide shuttling, mass loading. Herein, we develop a novel polyquaternium-10 (P10, cationic cellulose)-based binding system to simultaneously circumvent these issues. The water-borne P10 binder can suppress dissolution shuttling by not only adsorbing polyiodides via its quaternary ammonium groups oxygen heteroatoms but also eliminating use of toxic, expensive, I2-dissolving organic solvents (e.g., N-methylpyrrolidone, NMP), enabling facile green cathode-fabricating process. More importantly, is conducive preparation thick cathode coatings with loadings, thanks elasticity mechanical toughness after swelling electrolyte. As result, prepared demonstrate much better anti-self-discharge performance than those conventional PVDF binders (capacity retention: 84 vs 63% 200 h open-circuit storage). Even at an ultrahigh loading 14.5 mg cm–2, deliver significant specific capacity (216 mAh g–1) cyclability (96.8% remained 385 cycles). This should be highly compatible other performance-improving strategies, providing yet affordable approach for construction high-performance batteries.
