Abstract Although conversion‐type iodine‐based batteries are considered promising for energy storage systems, stable electrode materials scarce, especially high‐performance multi‐electron reactions. The use of tin‐based iodine‐rich 2D Dion–Jacobson (DJ) ODASnI 4 (ODA: 1,8‐octanediamine) perovskite as cathode is suggested. As a proof concept, organic lithium‐perovskite and aqueous zinc‐perovskite fabricated they can be operated based on the conventional one‐electron advanced two‐electron transfer modes. active elemental iodine in provides capacity through reversible I − /I + redox pair conversion at full depth, rapid electron injection/extraction leads to excellent reaction kinetics. Consequently, high discharge plateaus (1.71 V vs Zn 2+ /Zn; 3.41 Li /Li), large (421 mAh g −1 ), low decay rate (1.74 mV ) achieved lithium zinc ion batteries, respectively. This study demonstrates potential metal‐iodine batteries. Their reactions mechanism shed light similar battery systems aiming decent operational stability density.

Although their cost-effectiveness and intrinsic safety, aqueous zinc-ion batteries suffer from notorious side reactions including hydrogen evolution reaction, Zn corrosion passivation, dendrite formation on the anode. Despite numerous strategies to alleviate these have been demonstrated, they can only provide limited performance improvement a single aspect. Herein, triple-functional additive with trace amounts, ammonium hydroxide, was demonstrated comprehensively protect zinc anodes. The results show that shift of electrolyte pH 4.1 5.2 lowers HER potential encourages in situ uniform ZHS-based solid interphase Moreover, cationic NH4+ preferentially adsorb anode surface shield "tip effect" homogenize electric field. Benefitting this comprehensive protection, dendrite-free deposition highly reversible plating/stripping behaviors were realized. Besides, improved electrochemical performances also be achieved Zn//MnO2 full cells by taking advantages additive. This work provides new strategy for stabilizing anodes perspective.

Zn-metal batteries (ZnBs) are safe and sustainable because of their operability in aqueous electrolytes, abundance Zn, recyclability. However, the thermodynamic instability Zn metal electrolytes is a major bottleneck for its commercialization. As such, deposition (Zn2+ → Zn(s)) continuously accompanied by hydrogen evolution reaction (HER) (2H+ H2 ) dendritic growth that further accentuate HER. Consequently, local pH around electrode increases promotes formation inactive and/or poorly conductive passivation species (Zn + 2H2 O Zn(OH)2 on Zn. This aggravates consumption electrolyte degrades performance ZnB. To propel HER beyond potential (0 V vs standard (SHE) at 0), concept water-in-salt-electrolyte (WISE) has been employed ZnBs.
