However, their cycling performance is limited due to the decomposition of organic solvent electrolytes at the cathode/electrolyte interface and the dissolution of active materials during cycling, especially at elevated temperatures (above 60 °C). To address these challenges, a thermally stable, organic solvent-free electrolyte (OSFE) composed of three low melting alkali perfluorinated sulfonimide salts is developed, which helps to minimize the undesirable solvent decomposition. Additionally, chemical vapor deposition technology is employed to apply a conformal carbon coating to a representative MF, NiF2, effectively preventing the dissolution of active materials. The synergistic effect of OSFE and carbon coating enables a previously uncyclable NiF2 cathode, which exhibits a high reversible discharge capacity of 450 mAh g−1 after 160 cycles at 80 °C. Moreover, by incorporating 10 wt.% Li10GeP2S12 (LGPS) into the OSFE, the cycle number of NiF2 is extended to 300 cycles, maintaining an impressive discharge capacity of 350 mAh g−1 at 60 °C. These advancements highlight the potential for successful operation of MFs at elevated temperatures using OSFE, paving the way for their practical applications and future commercialization.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"37 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143798203","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, the dynamic solid electrolyte interphase (SEI) is adversely affected by LiTFSIprecipitation/dissolution and continuous reforming issues, causing electrolyte dryness. Here, the aminopolycarboxylic (Ethylenediaminetetraacetic acid, EDTA) additive is introduced to WIS electrolytes. An intriguing solvation phenomenon is observed wherein EDTA exhibited insolubility in a low-concentrated (7m) solution while achieving certain solubility in a high-concentrated (21m) one. The assembled full cell with EDTA exhibited good cycling stability at a low 0.5 C. To elucidate the unique solvation phenomenon and unravel the mechanism of SEI formation, experimental characterizations, and simulations are conducted. Molecular Dynamics (MD) and physical measurements disclosed that sufficient Li+ acts as a bridge connecting EDTA with TFSI−-H2O. The simulated electrode/electrolyte interface investigated the dynamics, showing the difference in the activity and density of molecules after adding EDTA. Density Functional Theory (DFT) calculations together with physical measurements discovered EDTA- species are prone to facile reduction during cycling, and the products facilitated the formation of a robust fluorine–oxygen–sulfur-based SEI, outstanding critical roles of EDTA in forming the interphase compared with the unstable dynamic SEI.

A one-step antisolvent-free methodology is developed, guided by the strategy of minimizing solvent toxicity and enhancing device performance. This method employs N,N-dimethylacetamide (DMAc) and N,N'-dimethylpropyleneurea (DMPU) as alternatives to DMF/NMP in antisolvent-free perovskite fabrication, along with ethanol for the hole transport layer. However, formamidinium (FA)-based perovskite films prepared via an antisolvent-free process often suffer from severe crystallization issues at the buried interface, which lacks rapid solvent removal and leads to a high concentration of defects such as uncoordinated Pb2+ ions. To surmount this challenge, a strategy is devised that paired the use of mixed solvents (DMAc/DMPU) with the incorporation of stable radical additives, featuring Cl, methoxy, or methylthio groups. This approach effectively modulates the crystallization dynamics, diminishes defect concentrations, and enhances the extraction of charge carriers. Employing this method, an efficiency of 25.02% is achieved, along with exceptional operational stability. This breakthrough represents a pivotal leap forward in the realm of sustainable photovoltaics, offering a promising path toward a greener energy future.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"24 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143798199","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, the lack of knowledge of the reaction kinetics makes the solar cell performance lag behind its solution-processed counterpart. Herein, the perovskite formation and crystal growth process in the CVD process are studied by unraveling the mechanism of ion diffusion via tracking the vapor–solid reaction with various semi-in-situ characterizations. It is found that Cs+ can migrate along the perovskite lattice and uniformly distribute in the vertical direction of the final perovskite film even changing the deposition order of CsBr and PbI2 in the solid source, whereas this order can significantly affect the growth kinetics and the bandgap of the perovskite. Depositing CsBr before PbI2 results in a faster conversion of inorganic precursors to perovskite phase, yielding a wider bandgap perovskite. Finally, we fabricated semi-transparent perovskite cells using all-vapor deposition process, which showed a champion efficiency of 18.7% and it retained ≈94% of its initial performance after 200 h of continuous operation. Moreover, using this all-vapor deposition process, we achieved a champion efficiency of 26.9% for monolithic perovskite-silicon tandem solar cells.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"183 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143806006","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, fluorination in the DRX bulk remains a challenge for scalable solid-state synthesis. In this study, a tailored reaction pathway is proposed to synthesize a highly fluorinated DRX. It is demonstrated for the first time that the unconventional precursors, Li6MnO4, MnF2, and TiO2, can avoid the formation of Mn-based intermediates (such as Li2(Mn,Ti)O3, LiMnO2, and Mn3O4), which, once formed, persist until the synthesis temperature reaches close to or above that required for fluorine volatility. Therefore, this method can form a highly fluorinated DRX with a composition of Li1.23Mn0.40Ti0.37O2−yFy (y = 0.29–0.34) at a low temperature (800 °C) relative to that required for conventional DRX solid-state reactions (≥900 °C). Li1.23Mn0.40Ti0.37O2−yFy (y = 0.29–0.34) delivers a specific capacity above 300 mAh g−1 and a specific energy of 980 Wh kg−1 at 30 °C.

However, this remains a significant challenge due to the high sensitivity of the perovskite crystallization process to humidity. Here, the synergistic effects of residual solvent and environmental humidity on the crystallization process of perovskite films are studied. The high water-solubility and volatility of the residual isopropanol (IPA) solvent in precursor film are major contributions to water sensitivity and poor control over the crystallization process. A solvent environment engineering is proposed to improve the reproducibility of PSCs fabricated in air. A low-water-solubility and low-boiling-point solvent, isobutanol (IBA), is introduced to inhibit water intrusion and prolong the crystallization process through slow evaporation. This approach facilitates the production of high-quality perovskite films (1.56–1.57 eV) and PSCs across a broad humidity range (20–80% RH), consistently achieving efficiencies exceeding 21%. Notably, devices prepared in the air at 60% RH achieve a high PCE of 25.1%.

However, the effective utilization of sulfur is challenging due to the difficulties in forming an intimate triple-phase interface between the electronic conductors, ionic conductors, and sulfur. In this study, high-performance ASSLSBs are achieved through a simple two-step mixing method that combines 1) high-energy ball milling and 2) mild mixing of a sulfur/carbon composite with Li6PS5Cl (LPSCl). This approach reduces the particle size, enhances the mixing uniformity, and activates the redox reaction of LPSCl while preserving its superionic conductivity, ultimately creating well-distributed conduction pathways in thick electrodes. During the milling, a catenation reaction between sulfur and LPSCl leads to the formation of inorganic Li-ion-conducting species, improving the ionic contact of sulfur. Moreover, the S–S bridging and cleavage reactions of the oxidatively decomposed LPSCl contribute reversibly to the additional capacity within the operating voltage range. Consequently, the optimal ASSLSB demonstrated a high areal capacity of 10.1 mAh cm−2, retaining 92.0% of its initial capacity after 150 cycles at 30 °C.
