Functional hydrogel electrolytes can regulate these coupled processes through solvent confinement, ion-selective transport, and mechanically persistent electrode contact. This review critically examines recent advances in hydrogel electrolytes for Zn–I2 batteries from interfacial chemistry to architectural engineering. Distinct from broader hydrogel reviews for aqueous Zn batteries, it focuses on the chemically asymmetric coupling between a water-reactive Zn anode and a soluble polyiodide cathode and organizes the field through a structure–mechanism–performance framework that links molecular affinity, fixed charge, and water-state regulation to measurable interfacial parameters, spatially decoupled architectures, and scale-relevant device metrics.

Over the past decade, electrolyte engineering has emerged as a key strategy to address these challenges. This review summarizes the development of fast-charging electrolytes over the past ten years and outlines a design framework. Electrolyte formulations are first deconstructed into their main components—solvents, salts, and functional additives—and representative strategies for tuning solvation structure and interphase chemistry are discussed to suppress Li plating and improve interfacial kinetics. The discussion then extends to advanced electrolyte systems, particularly localized high-concentration electrolytes (LHCEs), and their compatibility with different anode chemistries. Advanced characterization techniques are also summarized and categorized based on destructiveness, spatial and temporal resolution, quantitative analysis, and the chemical species or processes probed across multiple length scales. Recent progress in AI-enabled electrolyte discovery and battery management system (BMS) strategies for optimized fast-charging protocols is further highlighted.

In particular, hetero-grain boundaries (h-GBs) such as Li2O/LiF or Li2CO3/LiF are theoretically recognized to provide favorable Li-ion pathways within inorganic LEI; however, experimental verification of h-GB-mediated Li-ion transport remains elusive. In this study, we provide experimental evidence for favorable Li-ion transport associated with h-GBs using a tailored h-GB-rich MgO/MgF2 heterostructure (MgO/F). Multifaceted analyses indicate that the MgO/MgF2 heterointerfaces establish a favorable Li-ion transport environment through coupled interfacial effects, with the enhanced defect population potentially contributing to increased Li-ion carrier availability. Furthermore, upon contact between the Li substrate and the MgO/F layer acting as the LEI, the MgO/F layer spontaneously constructs a dual-interfacial architecture: an inorganic-rich solid electrolyte interphase abundant in h-GB-rich Li2O/LiF and a Li/substrate interphase consisting of a Li-Mg alloy with rapid Li surface migration. This synergistic interfacial architecture maximizes the practical efficacy of h-GB-rich MgO/F for stabilizing Li metal anodes. Consequently, the h-GB-rich MgO/F demonstrates exceptional electrochemical stability, significantly outperforming bare Li in both symmetric and full cells. This study provides experimental insight into the role of h-GBs in inorganic interfaces and provides a strategic blueprint for designing highly stable LMBs.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e75383"},"PeriodicalIF":29.1,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149178174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although multimetal materials can catalyze both pathways, the parallel reactions typically occur at different active sites, and their relative contributions are often governed by catalyst composition and active-site distribution, making deliberate regulation of pathway competition difficult. Here, we propose a multimetal catalyst with an electronically asymmetric Fe─O─Co interface to enable pathway divergence within a Co-centered catalytic environment. Fe introduction into CoNi layered hydroxides leads to electron density redistribution at neighboring Co sites and shifts PMS activation from a high-valent CoIV═O-biased route toward a sulfate-radical-enriched regime while retaining complementary nonradical oxidation. The optimized catalyst achieved 1.43-fold greater TOC removal and a 1.47-fold higher PMS utilization efficiency (PUE) for norfloxacin (NOR) degradation than the Fe-free control, with robust decontamination performance against common background matrix interference and sustained activity over 96 h of high-flux continuous-flow operation. This work establishes interfacial Fe regulation as a pathway-engineering strategy for steering oxidant-activation selectivity through heterometal-induced electronic asymmetry, providing a route to reconcile mineralization depth with matrix tolerance in Fenton-like water treatment.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e75324"},"PeriodicalIF":29.1,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149178210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
