Stable Zinc Electrode Reaction Enabled by Combined Cationic and Anionic Electrolyte Additives for Non‐Flow Aqueous Zn─Br₂ Batteries

Aqueous zinc-bromine batteries hold immense promise for large-scale energy storage systems due to their inherent safety and high energy density. However, achieving a reliable zinc metal electrode reaction is challenging because zinc metal in the aqueous electrolyte inevitably leads to dendrite growth and related side reactions, resulting in rapid capacity fading. Here, it is reported that combined cationic and anionic additives in the electrolytes using CeCl
