Aqueous zinc ion batteries (AZIBs) are attracting increasing research interest due to their intrinsic safety, low cost, and scalability. However, the issues including hydrogen evolution, interface corrosion, and zinc dendrites at anodes have seriously limited the development of aqueous zinc ion batteries. Here, N,N-methylenebis(acrylamide) (MBA) additives with −CONH- groups are introduced to form hydrogen bonds with water and suppress H2O activity, inhibiting the occurrence of hydrogen evolution and corrosion reactions at the interface. In situ optical microscopy demonstrates that the MBA additive promotes the uniform deposition of Zn2+ and then suppresses the dendrite growth on the zinc anode. Therefore, Zn//Ti asymmetric batteries demonstrate a high plating/stripping efficiency of 99.5%, while Zn//Zn symmetric batteries display an excellent cycle stability for more than 1000 h. The Zn//MnO2 full cells exhibit remarkable cycling stability for 700 cycles in aqueous electrolytes with MBA additives. The additive engineering via MBA achieved the dendrite-free Zn anodes and stable full batteries, which is favorable for advanced AZIBs in practical applications.

Despite the numerous advantages of abundant zinc resources, low redox potential, and affordability, aqueous zinc-ion batteries (AZIBs) currently face limitations due to dendritic growth and side reactions. This study explores the use of low-cost and efficient anionic dyes, specifically Direct Red 80 (DR80) as dual-functional electrolyte additives to enhance the electrochemical performance of AZIBs and facilitate the reuse of dye wastewater. Experimental and theory calculation results all demonstrate that the DR80 molecules readily adsorb onto the surface of the zinc anode, creating a stable and robust solid electrolyte interphase layer. This layer acts as a protective barrier, effectively mitigating H + attacks and reducing both hydrogen evolution and corrosion reactions. Additionally, it covers any initial protrusions on the zinc anode, preventing the occurrence of the "tip-effect" phenomenon and limiting access of water to the zinc anode, thereby minimizing water decomposition. Moreover, the sulfonic acid groups of DR80 molecules displace some water molecules in [Zn(H 2 O) 6 ] 2+ , disrupting the original solvent sheath and reducing water decomposition. Especially, using the DR80 additive, the Zn/Zn cell reaches an impressive cycle life of 1500 h at 2 mA cm −2 @1 mAh cm −2 . Given the low cost and widespread availability, this additive shows great potential in the future practical implementation of AZIBs.

Aqueous zinc‐ion batteries (AZIBs) hold great potential for grid‐scale energy storage systems, owing to their intrinsic safety and low cost. Nevertheless, their industrialization faces challenges of severe Zn dendrites and parasitic reactions. In this study, sulfonated cellulose separator (denoted as CF‐SO3) with low thickness, exceptional mechanical strength, and large ionic conductivity is developed. Benefiting from the electrostatic repulsion between ─SO3− functional groups and SO42− anions and the strongly interaction between ─SO3− and Zn2+ cations, the migration of SO42− anions can be restricted, the 2D diffusion of Zn2+ ions at the surface of Zn electrode can be suppressed, and the desolvation of hydrated Zn2+ ions can be promoted. Concurrently, the homogeneous nanochannels within CF‐SO3 separator can ensure uniform electric field and Zn2+ ion flux. With these benefits, the CF‐SO3 separator enables Zn//Zn cells to run stably for 1200 h at 4 mAh cm−2 by facilitating oriented and dendrite‐free Zn deposition. Under a large depth of discharge of 68.3%, a life span of 400 h can still be achieved. Additionally, the reliability of CF‐SO3 separator is confirmed in Zn//MnO2 and Zn//H11Al2V6O23.2 full batteries with high mass loading conditions. This work provides valuable guidance for the advancement of high‐performance separators of AZIBs.
