The practical applications of aqueous zinc-ion batteries (AZIBs) have been restricted by the fast growth Zn dendrites and severe side reactions at Zn/electrolyte interface. Herein, a multifunctional additive, L-leucine (Leu), is incorporated into mild acidic electrolyte to stabilize anode. Leu molecule, featuring both carboxyl amino groups, exhibits strong interactions with Zn2+, which can reshape solvation structure Zn2+ facilitate uniform electrodeposition Zn. Simultaneously, molecule preferential adsorption onto surface, effectively isolating it from direct contact water, thus suppressing unwanted reactions.

The solar-driven photorechargeable zinc-ion batteries have emerged as a promising power solution for smart electronic devices and equipment. However, the subpar cyclic stability of Zn anode remains significant impediment to their practical application. Herein, poly(diethynylbenzene-1,3,5-triimine-2,4,6-trione) (PDPTT) was designed functional polymer coating Zn. Theoretical calculations demonstrate that PDPTT not only significantly homogenizes electric field distribution on surface, but also promotes ion-accessible surface With multiple N C=O groups exhibiting strong adsorption energies, this reduces nucleation overpotential Zn, alters diffusion pathway

Abstract The development of flexible zinc-ion batteries (ZIBs) faces a three-way trade-off among the ionic conductivity, Zn 2+ mobility, and electrochemical stability hydrogel electrolytes. To address this challenge, we designed cationic named PAPTMA to holistically improve reversibility ZIBs. long branch chains in polymeric matrix construct express pathways for rapid transport through an repulsion mechanism, achieving simultaneously high transference number (0.79) conductivity (28.7 mS cm −1 ). Additionally, reactivity water hydrogels is significantly inhibited, thus possessing strong resistance parasitic reactions. Mechanical characterization further reveals superior tensile adhesion strength PAPTMA. Leveraging these properties, symmetric employing deliver exceeding 6000 h reversible cycling at 1 mA −2 maintain stable operation 1000 with discharge depth 71%.

Abstract The zinc dendrite growth and the parasitic hydrogen evolution reactions (HER) hinder commercialization of batteries. To address this, a hydroxyl‐rich Boehmite coating (HR‐BC) strategy is developed that combines excellent electrical insulation high ion conductivity. hydrophilic hydroxyl groups facilitate bond formation with hydrated ions, accelerating de‐solvation process suppressing HER. Additionally, electrically insulative nature prevents reduction ions within HR‐BC results in preferential Zn deposition underneath it, leading to dendrite‐free “sandwich structure” HR‐BC//Zn deposition//Zn foil. Symmetric cells using HR‐BC‐Zn electrodes obtain an ultralong stable cycling lifetime 1700 h at 5 mA cm −2 , along cumulative plating capacity 4250 mAh . When paired V 2 O cathode, anode demonstrates capacitance retention 90% average Coulombic efficiency (CE) 99.8% after 4000 cycles.

Abstract Aqueous zinc‐ion batteries have garnered significant interest due to their inherent safety, cost‐effectiveness, and high capacity. However, water molecules in the electrolyte adsorb onto surface of negative zinc electrode via hydrogen bonding dissociate into H + OH − under an electric field. This creates a local alkaline environment at interface, promoting dendrite growth, corrosion, evolution reaction. Herein, bond competition strategy for optimizing aqueous electrolytes based on low‐cost polyhydroxyl organic additive maltitol is proposed.
