This thermodynamic stability can be lost by the presence of dopants which are required to stabilize the cubic phase of LLZO and can be reduced by lithium metal. However, the role of oxygen in such reactions is taken for granted. In this work, the reduction of Nb-substituted LLZO (Nb-LLZO) is explored by Li metal and shows that interfacial reactions propagate and lead to the decomposition with substantial Nb<sup>5+</sup> reduction deep into the bulk electrolyte. Scanning Transmission Electron Microscopy with Energy Dispersive X-ray Spectroscopy and thermogravimetric analyses show much of the reduction is due to oxygen vacancies formed, leading to increased electronic conductivity mapped with conductive Atomic Force Microscopy. Density functional theory calculations indicate oxygen release is favored by increased excess lithiation of Nb-LLZO. Electrochemical impedance of polycrystalline Nb-LLZO shows the continuous evolution of ionically resistive interphases near the lithium metal interface with Nb-LLZO while single crystals show little reactivity at room temperature and self-limiting reduction at 60°C.

Among these metrics, the dark current density stands out for its direct impact on the sensitivity of the detectors. In this study, an anomalous illumination‐sensitive variation in dark current is observed in fabricated near‐infrared OPDs, which undermines the device reliability. The systematic investigation reveals that this behavior stems from the photocatalytic nature of zinc oxide (ZnO), the electron transport layer used in the OPD. The photocatalytic nature of ZnO detrimentally affects the stability of the active material, particularly the nonfullerene acceptor employed in this study. Through robust interface engineering approach, which involves modifying the interface between ZnO and the active layer, the anomalies in the dark current are successfully mitigated, enhancing the consistency and reliability of the OPDs. In addition to reducing the dark current, this interface engineering strategy improves the overall performance and operational stability of the OPDs, especially under ultraviolet exposure.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"68 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866657","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}

A novel high-entropy doping strategy is developed using a scalable ball-milling method to form a solid solution of doped elements (cation dopants: Ni, Mo, Cr, W, and Si; anion dopant: Se) with the primary components (iron and sulfur). Simultaneously, expanded graphite (EG) is incorporated and exfoliated through ball milling to provide abundant active sites for the growth of high-entropy-doped FeS during the subsequent high-temperature vulcanization process.
