Herein, a closed‐loop iodide‐oxygen cycle mechanism for a neutral aqueous Zn–air/iodide hybrid battery (ZAIB), integrating oxygen and iodide redox chemistry, is proposed. A multifunctional electrocatalyst, featuring FeN nanoparticles anchored on a hierarchically porous carbon matrix, is designed to drives oxygen reduction reactions (ORR) and iodide oxidation/reduction reactions (IOR/IRR). This catalyst spatially confines zinc hydroxyacetate dihydrate (ZHA) precipitates within its honeycomb meso‐macroporous framework, thereby preserving triple‐phase boundaries. During discharge, I– generated from I3– reduction enhances the kinetics, thereby increasing discharge voltage. Concurrently, OH– formed during ORR reacts with the electrolyte to produce ZHA. Upon charging, thermodynamically favored low‐potential IOR dominates, regenerating I3– from I– and decomposing ZHA to release OH–. The released OH– then spontaneously reacts with I3– to regenerate I– and evolve O2, resulting in a reduced charge voltage. Consequently, the neutral ZAIB achieves a low charge/discharge voltage gap (640.1 mV), high energy efficiency (54.0%), and exceptional stability (>1800 h at 2 mA cm−2). This synergistic mediator‐catalyst codesign strategy offers a viable pathway to high‐performance neutral metal–air systems.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"35 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144987529","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}

However, it falls short of the long‐term durability of pure graphite, and research on their cycling performance remains limited. This study observes a sudden capacity decay in graphite/SiO anodes during long‐term cycling at room temperature (RT) and a moderate C‐rate. This decay arises from the mechanical degradation of SiO, leading to the formation of a “SiO‐SEI crust” that consumes lithium ions. This phenomenon does not occur at higher temperatures or lower C‐rates, implying that larger diffusion‐induced stress from lithium‐ion gradients at RT and 1 C accelerates SiO degradation. Furthermore, introducing a relaxation step to reduce the lithium‐ion gradient mitigates this sudden capacity decay, supporting diffusion‐induced stress as a critical factor in the degradation mechanism. These findings emphasize the role of diffusion‐induced stress in the performance degradation of Si‐based batteries and provide valuable insights for enhancing the lifespan of composite anodes.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"24 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144987526","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}

Notably, the PCNFs scaffold offers a porous conductive framework in which the MXene component effectively suppresses polysulfides diffusion, and surface‐anchored MoSe2 nanosheets strategically expose catalytically active sites while preventing insulation caused by Li2S accumulation.

While zinc electrodeposition kinetics (i0, Zn2+/Zn0) have been extensively studied, direct quantification of HER kinetics (i0,HER) during zinc electrodeposition remains elusive. Common approaches in literature decouple HER from zinc electrodeposition, measuring i0,HER in inert electrolytes without zinc ions. This fails to capture the true electrochemical environment and can lead to misleading conclusions regarding HER kinetics during zinc electrodeposition. Here, we introduce a novel method that combines electrochemical mass spectrometry (EC‐MS) with electrochemical measurements to quantify HER kinetics directly and simultaneously during zinc electrodeposition by real‐time monitoring of evolved H2 gas. This approach captures the true i0,HER under coupled reaction dynamics and reveals the limitations of conventional decoupling strategies. The platform enables rapid screening of current collectors and electrolyte additives, offering unprecedented insight into the interplay between the HER and zinc electrodeposition. Combined, this strategy provides a powerful framework for the rational design of materials and chemistries that enhance the stability and efficiency of AZMBs.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"33 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144987343","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}
