However, these advantages are offset by critical challenges, most of which stem from issues at the solid electrolyte–electrode interface. These challenges include interfacial instability, non-uniform lithium deposition during initial charging, and void formation owing to volumetric changes during cycling. Meanwhile, thin-film AFASSBs (TF-AFASSBs), fabricated by implementing the anode-free design in thin-film battery systems, offer distinct advantages over conventional thin-film systems, including higher energy density and a more streamlined cell structure. Moreover, their fabrication using deposition-based approaches promotes better interfacial wettability, thereby enhancing contact between the solid electrolyte and current collector. Despite these advantages, however, TF-AFASSBs are often more susceptible to interfacial degradation and uneven lithium plating than their bulk-type counterparts. In response to these challenges, considerable research has focused on mitigating interfacial and mechanical failures in both AFASSBs and TF-AFASSBs. This review presents an overview of the core characteristics and key limitations of AFASSBs and discusses recent advances in material development and interfacial engineering. These insights aim to guide the development of effective strategies for meeting the performance and stability requirements of practical TF-AFASSBs.</p>","PeriodicalId":100671,"journal":{"name":"InfoScience","volume":"3 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inc2.70009","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148358048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The technology has been discussed in detail, including its applications in materials development, the sustainable circular economy, polymer creation, biomaterials production, and additive manufacturing optimization. The combination of multitask deep neural networks, graph neural networks, and transformer-based architectures with SMILES strings and molecular graphs has enabled ML algorithms to predict thermal, mechanical, electrical, and optical properties with high performance. The field requires standardized data as its foundation, sourced from major databases (e.g., PoLyInfo and PI1M) to improve property predictions in computational systems. Researchers employ graph-based models, topological indices, and ML to design polymers via optimized closed-loop systems that track processes in real time. The development of polymer informatics faces two primary obstacles: researchers lack access to sufficient standardized, high-quality datasets, and they struggle to represent polymer structures effectively (e.g., BigSMILES).

Given the growing significance of organic photocatalysts in H₂O₂ synthesis, a comprehensive review of this field has become imperative. This paper offers a systematic examination of visible-light-driven H₂O₂ synthesis using various organic photocatalysts, including graphitic carbon nitride (g-C₃N₄), resorcinol-formaldehyde (RF) resin, covalent organic frameworks (COFs), and linear conjugated polymers (LCPs). The focus lies on fundamental mechanistic elucidation, design of reaction pathways and active sites, modification strategies, and establishment of efficient photocatalytic systems. Extensive studies have correlated photocatalytic efficiency with interfacial electron transfer kinetics and spatial charge separation. Therefore, we methodically analyze key determinants governing photogenerated carrier dynamics and present engineering strategies for performance enhancement.
