Abstract Zinc‐halogen batteries are promising for sustainable energy storage, offering high redox capacities at economical price points. However, they hindered by issues such as the irreversibility caused dissolution of intermediates and sluggish charge transfer, which limit their widespread adoption. Addressing these issues, bismuth‐iodide perovskite cathodes employed a halogen element enriched model system. These demonstrate considerable anion capacities. In combined simulation experimental study, it is uncovered that (BAD)BiI 4 (BAD + denotes benzamidinium) cathode, greatly improves interactions with iodine species boosts transfer capability compared to its (BA)BiI (BA benzylaminium) counterpart. enhancements can be attributed synergistic effects arising from stronger Bi−I···I bonds C═N─H···I hydrogen bonds. The cathode attains reversible I − /I 0 chemistry 92% capacity retention after 30 000 cycles current density 10 A g −1 , outperforming previously reported batteries. Additionally, defect‐tolerant property conversion elucidated. 5 forms notably bond in comparison 3 effectively mitigates polyiodide shuttling. advantageous characteristics highlight promise adaptability developed high‐performance chemistry.

Regulating work functions (WF) FTO electrodes through energy levels, band bends upwards with a small offset for ITO/IDCz‐3/perovskite, thereby promoting hole extraction blocking electrons. As result, PSC employing IDCz‐3 as hole‐collecting layer exhibits champion PCE 25.15%, is record multipodal SAMs‐based PSCs.
