Aqueous zinc–iodine batteries (ZIBs) based on the reversible conversion between various iodine species have garnered global attention due to their advantages of fast redox kinetics, good reversibility, and multielectron feasibility. Although significant progress has been achieved in ZIBs with two-electron I–/I2 pathway (2eZIBs), relatively low energy density hindered practical application. Recently, four-electron I–/I2/I+ electrochemistry (4eZIBs) shown a improvement density. Nonetheless, use 4eZIBs is challenged by poor reversibility polyiodide shuttling during I+ hydrolysis I2/I+ conversion. In this Review, we thoroughly summarize fundamental understanding two ZIBs, including reaction mechanisms, limitations, strategies. Importantly, provide an intuitive evaluation assess potential highlight critical impacts Zn utilization rate. Finally, emphasize cost issues associated electrodes propose closed-loop recycling routes for sustainable storage ZIBs. These findings aim motivate application advanced promote storage.

Abstract Aqueous zinc‐ion batteries represent a highly promising next‐generation electrochemical energy storage system because of their safety, environmental friendliness, resource abundance, and simple assembly conditions. However, the formation growth zinc dendrites on anode seriously hinder practical application batteries. Zincophilic design, which enables uniform nucleation/deposition, offers an effective solution to achieve dendrite‐free anodes. Despite significant progress in field zincophilic research this currently lacks clear analysis guidance. This paper provides comprehensive overview current status design mechanism for from three aspects: construction layers, addition additives electrolyte, 3D host. Moreover, challenges facing industrialization commercialization further are briefly discussed.

Abstract Anode‐free aqueous zinc (Zn) metal batteries (AFZMBs) possess an optimal battery architecture configuration because no excess Zn source is involved in the charge/discharge processes, rendering it feasible to enhance energy density of batteries. However, rapid capacity fading due unstable anode‐side current collector/electrolyte interfacial chemistry, which results dendrite growth, impedes their practical application, especially quasi‐solid‐state AFZMBs.

Aqueous zinc-iodine (Zn-I2) batteries with four-electron (4e) I-/I0/I+ conversion (4eZIBs) offer high energy density but face significant challenges for application, including the polyiodide shuttle effect and I+ hydrolysis I2 cathodes poor reversibility Zn anodes. Here, we report a coordination chemistry strategy to address these issues simultaneously by introducing hexamethylenetetramine (HMTA) as an electrolyte additive. In aqueous electrolytes, HMTA undergoes protonation form positively charged nitrogen moieties that effectively precipitate polyiodides species (ICl2-) mitigate hydrolysis. This enables 4eZIBs achieve near-theoretical specific capacity of 425 mA h g-1 (based on mass iodine) Coulombic efficiency (CE) exceeding 99%. On anode, preferentially adsorbs onto its surface, inhibiting competitive water adsorption suppress both dendrite formation hydrogen evolution. As result, first time, durable 4eZIB performance in pouch-cell configurations limited supply.
