Abstract Developing sustainable energy storage systems is crucial for integrating renewable sources into the power grid. Aqueous zinc‐ion batteries (ZIBs) are becoming increasingly popular due to their safety, eco‐friendliness, and cost‐effectiveness. However, challenges remain in achieving realistic time per charge, long cycling life, high capacity practical conditions. Despite advancements cathode materials, issues such as dissolution side reactions limit performance. Optimizing architecture electrolyte composition essential address these challenges. Tailored formulations can stabilize electrode‐electrolyte interface (EEI enhance stability. This perspective reviews cathodes from past decades compares performance under different current densities. Emphasizing low density extended stability widespread adoption of ZIBs grid‐scale applications. By focusing on aspects, this aims bridge gap between research applications, offering insights optimizing material structure selecting matching electrolytes storage. work guides future developments ZIB technology, facilitating transition lab real‐world deployment.

Rechargeable aqueous zinc-ion batteries (AZIBs) draw much attention for low cost and high safety. However, hydrogen evolution reaction (HER) uneven Zn2+ deposition shorten lifespan, hampering commercial use. In this study, sodium dehydroacetate (SD) containing carbonyl keto-carbonyl is introduced as multifunctional electrolyte additives, which effectively modifies the solvent shell structure, achieving a transference number of up to 0.72. Acting bond acceptor, SD disrupts water network thereby increasing HER overpotential by 22 mV corrosion potential 9 mV. The polar functional groups in can reversibly capture H⁺ ions dynamically neutralize OH⁻ ions, maintaining interfacial pH balance on zinc anode suppressing HER. Notably, not only alters electrolyte's kinetic but also induces uniform along (002) plane, inhibiting dendrite growth minimizing side reactions. This phenomenon demonstrated both symmetric full-cell configurations. Zn//Zn cell achieves an ultra-long cycling lifespan 2800 hours at 5 mA cm⁻2, Zn//VO2 full battery maintains capacity retention rate 73.09% after 2000 cycles with average coulombic efficiency 99.98%, underscoring effectiveness additive enhancing performance.

Abstract Disordered electrodeposition of Zn 2+ resulted in serious dendrite and hydrogen evolution reactions, greatly decreasing the energy efficiency durability aqueous zinc ion batteries (AZIBs). Herein, sodium 2‐mercaptoethanesulfonate (MSN) is proposed as a new additive to achieve induced directional on (101) crystal surface form dense uniform metal layer via cooperative effect sulfhydryl sulfonic acid groups. Different from reported additives, MSN molecules promote rapid formation adsorption layer, which accelerates its directed migration rate orderly nucleation process, achieving eliminated dendrites overpotential, far superior additives. The MSN‐introduced Zn||Zn symmetric battery displays amazing stably cycled for more than 3500 h at 2 mA cm −2 @ mAh , over 1 000 even under harsh conditions (5 5 ). Furthermore, Zn||δ‐MnO coin offers high capacity 201.5 g −1 low recession 1% during 800 cycles A higher that blank sample (121.3 56.1%), respectively, fully demonstrating extraordinary advantages contributions molecules.
