However, the low Mn<sup>2+</sup>/MnO<sub>2</sub> conversion efficiency caused by incomplete MnO<sub>2</sub> dissolution hinders its practical applications. Recently, redox mediation chemistry has been introduced to improve Mn<sup>2+</sup>/MnO<sub>2</sub> conversion capacity by orders of magnitude. However, as an emerging key strategy, the complex solid–liquid conversion mechanism, the interactions between the redox mediator and the Mn-based species, and the influence of the interfacial environment remain poorly understood. This perspective article aims to discuss critical evaluation criteria, outline key research directions, and summarize relevant characterization methods for redox mediation chemistry in Mn<sup>2+</sup>/MnO<sub>2</sub> conversion. Several future focuses on design principles for high-energy Mn-based cathode materials are proposed. We hope to use a Mn<sup>2+</sup>/MnO<sub>2</sub> system as a model platform to deepen scientific understanding of redox-mediated conversion reactions and inspire broader research in this field.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"34 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144305226","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, several challenges remain, such as low capacity, unsatisfactory energy density, and poor stability, which necessitate further research. Recently, defective engineering has emerged as a promising strategy in the development of ZIBs. This Review highlights the recent advancements in employing defective engineering toward high performing aqueous ZIBs, detailing its implications on various cathode, anode, electrolyte additives, current collectors, and separators. We will also discuss methodologies to incorporate defects and elucidate the underlying mechanisms by which defective engineering enhances battery performance. Furthermore, we outline future research directions of defective engineering in the development of aqueous zinc ion batteries.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"14 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144311891","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}

All-solid-state thin-film lithium batteries offer significant advantages in size and integration but are still subject to their low-voltage plateau (&lt;3.3 V) and microampere-level capacity (≤0.2 mWh). Herein, we proposed the crystal-facet engineering combined with the substrate anchoring effect to address critical structure variation in the 4.6 V LiCoO<sub>2</sub> film. The rotated (003) basal plane effectively relieves internal stress and the Li<sup>+</sup> migration energy barrier, contributing to strengthened continuous migration channels and a structure skeleton in Nb<sub>2</sub>O<sub>5</sub>@LCO nanosheets. Therefore, the additive-free full cell exhibits excellent cyclability, retains 72.5% capacity retention over 500 cycles at 1.4 C between 3.0 and 4.6 V, and has a high energy density of 1.148 mWh cm<sup>–2</sup> in a 3.5 cm<sup>2</sup> thin-film cell.

The molecular structure of these porous liquid-based electrolytes (PLEs) can be designed to provide permanent, empty, and selective porous media. In this Perspective, we show the potential and design principles of porous liquids (PLs) that can enable their incorporation into all ion batteries. The porous structure of PLs increases their surface area exposure to ions for their selective shielding from dendrite formation, enhancing their mobility/conductivity, thus also addressing challenges with thermal instability and safety risks associated with conventional electrolytes. This work proposes a roadmap for PLE development, emphasizing molecular design, target mechanisms, and computational studies aligned with specific battery chemistries to enhance the energy density and extended cycle life.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"14 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144305229","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}
