Abstract The feasibility of aqueous zinc‐ion batteries for large‐scale energy storage is hindered by the inherent challenges Zn anode. Drawing inspiration from cellular mechanisms governing metal ion and nutrient transport, erythritol introduced, a zincophilic additive, into ZnSO 4 electrolyte. This innovation stabilizes anode via chelation interactions between polysaccharides 2+ . Experimental tests in conjunction with theoretical calculation results verified that additive can simultaneously regulate solvation structure hydrated reconstruct hydrogen bond network within solution environment. Additionally, molecules preferentially adsorb onto anode, forming dynamic protective layer. These modifications significantly mitigate undesirable side reactions, thus enhancing transport deposition behavior. Consequently, there notable increase cumulative capacity, reaching 6000 mA h cm⁻ 2 at current density 5 cm −2 Specifically, high average coulombic efficiency 99.72% long cycling stability >500 cycles are obtained 1 Furthermore, full comprised MnO cathode an erythritol‐containing electrolyte deliver superior capacity retention. work provides strategy to promote performance anodes toward practical applications.

Zinc-bromine flow batteries (ZBFBs) hold great promise for grid-scale energy storage owing to their high theoretical density and cost-effectiveness. However, conventional ZBFBs suffer from inhomogeneous zinc deposition sluggish Br2/Br- redox kinetics, resulting in a short cycle life low power density. Herein, multiscale porous electrode with abundant nitrogen-containing functional groups is developed by growing zeolitic imidazolate framework-8 situ on graphite felts, followed facile carbonization process simultaneously tackle both the challenges. Theoretical experimental results reveal that exhibit adsorption toward atoms, while microstructures promote pore-level mass transport, thereby compact uniform deposition. In meantime, boosts reaction kinetics due its catalytic activity large surface area. As result, equipped optimized electrodes at negative positive sides can operate an ultrahigh current of 250 mA cm-2 maintaining efficiency 68.0%, far surpassing pristine felts (50.7%). Remarkably, battery exhibits excellent cycling stability over 2000 cycles without obvious decay. This study provides simple yet effective method developing high-performance critical challenges ZBFBs, promoting commercialization this promising technology.
