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.

Abstract Aqueous zinc metal batteries (AZMBs) are emerging as a powerful contender in the realm of large‐scale intermittent energy storage systems, presenting compelling alternative to existing ion battery technologies. They harness benefits zinc's high safety, natural abundance, and favorable electrochemical potential (−0.762 V vs Standard hydrogen electrode, SHE), alongside an impressive theoretical capacity (820 mAh g −1 5655 cm −3 ). However, performance ZMBs is impeded by several challenges, including poor compatibility with high‐loading cathodes persistent side reactions. These issues intricately linked inherent physicochemical properties anodes (ZMAs). Here, this review delves into traditional methods ZMAs production, encompassing extraction, electrodeposition, rolling processes. The discussion then progresses exploration cutting‐edge methodologies designed enhance ZMAs. categorized alloying, pre‐treatment substrate, advanced electrodeposition techniques, development composite utilizing powder. offers comparative analysis merits drawbacks various optimization strategies, highlighting beneficial outcomes achieved. It aspires inspire novel concepts for advancement innovation next‐generation zinc‐based solutions.
