💡 Novelty & Significance:
The novelty lies in using Bi₁₂.₆₇S₁₈Br₂ nanorods with iodide additive to create successive redox mediation via gradient-potential couples (I⁰/I⁻ > Bi³⁺/Bi⁰ > S⁰/S²⁻), accelerating sulfur kinetics and suppressing side reactions. This enables high-capacity aqueous Zn–S batteries (792 mAh g⁻¹, 488.2 Wh kg⁻¹) with practical pouch-cell cycling, offering a new design principle for energy storage.
