Abstract Aqueous Zn batteries, which use metallic as anodes, have gained significant attention due to their affordability and high safety standards. However, these anodes are plagued by issues such dendritic growth side reactions, including corrosion hydrogen evolution. One straightforward yet effective approach mitigate is apply protective coatings the enhance reversibility. It generally believed that layers should a affinity for Zn. Contrarily, this study proposes non‐conductive form strong binding with H + ions while maintaining weaker interaction 2+ ions, thereby ensuring higher selectivity over . This concept illustrated using zirconium dioxide (ZrO 2 ), an ionic conductor meets criteria effectively curbs reactions of Remarkably, coated ZrO layer demonstrate lifespan exceeding 6000 h at 1 mA cm −2 mAh , significantly outperforming uncoated ones, last <200 h. discovery introduces novel design principle insulating surface coatings, potentially applicable not only but also other metal anodes.

Zinc-ion batteries (ZIBs) are promising on account of the inherent safety, minimal toxicity, cost-effectiveness, and high theoretical capacity. However, critical issues including Zn dendrites side reactions impede their commercial application. Here, we propose green, non-toxic biological carrageenan (Carr) serving as an electrolyte additive to address aforementioned issues. Owing multifunctional groups, Carr has capacity interact with
