ZIF-8 interphase layer with sub-nano windows accelerates Li+ desolvation kinetics and thus suppresses unfavorable side reactions. Further, the internal cavities of ZIF-8 serve as an anion reservoir to modulate anion-reinforced solvation structure of Li+, facilitating the formation of LiF- and Li3N-riched solid–electrolyte interphase. Thus, the Li/Cu@ZIF-8 asymmetric cell exhibits remarkable Aurbach coulombic efficiency of 99.84%, and Cu@ZIF-8/LiFePO4 AFLMB delivers impressive capacity retention (57.8%) over 400 cycles.

To maximize the energy density, a key research interest lies in the development of ultrathin and highly conductive solid electrolyte (SE) layers. In this work, thin and flexible sulfide solid electrolyte membranes are fabricated and laminated onto a non-woven fabric using a scalable and solvent-free, continuous roll-to-roll process (DRYtraec). These membranes show significantly improved tensile strength compared to unsupported sheets, which facilitates cell assembly and allows a continuous component production using a single-step calendering process. By tuning the thickness, densified membranes with thicknesses ranging from 40 to 160 µm are obtained after a compression step. The resulting SE membranes retain a high ionic conductivity (1.6 mS cm−1) at room temperature.

However, the perceived poor rate capability of graphite has become a key concern for its commercial application in PIBs. Herein, the above understanding on the poor rate capability of graphite is updated. Without modifying graphite structure, by simply introducing a tin trifluoromethanesulfonate (Sn(OTf)2) additive in phosphate-based electrolyte, the graphite in K||graphite half-cell can deliver a capacity of 240 mAh g−1 at a high rate of 2 C (1 C = 279 mA g−1) and operates for 1000 cycles with negligible degradation. Moreover, an unprecedented rate capacity of ≈200 mAh g−1 for graphite anode at 4 C is achieved in a three-electrode K|K ref|graphite cell configuration where the interference of the K metal counter electrode is eliminated. Unlike structure modification strategies, such remarkable rate performance is originated from the low-impedance inorganic-rich KF/SnF2 hybrid interphase on graphite. Thus, the effectiveness of the electrolyte regulation strategy highlights the underestimated rate capability of graphite anode. This renewed insight dispels the concern regarding the commercial applicability of graphite anode and enriches the advantages of PIBs for high-power density.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"6 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142940200","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, its strong coordination with iodoplumbate makes it difficult to remove during film formation, resulting in defects and voids at the perovskite-substrate interface, which compromise efficiency and long-term stability. Here ethyl acrylate (EA), an unsaturated monomer that aids in the effective removal of DMSO from the perovskite film is introduce. EA forms a complex with DMSO, facilitates DMSO de-intercalation, and enhances the co-evaporation process thanks to its low boiling point. Additionally, by incorporating a small amount of the initiator azobis (isobutyronitrile) (AIBN), EA is successfully polymerized into polyacrylate ethyl ester (poly-EA) during crystallization. The evaporated EA helps remove DMSO, while the poly-EA passivates defects in the perovskite films. This dual-function strategy significantly improves device performance, resulting in efficiencies of 25.4% for small-area devices and 20.3% for 15 cm2 mini-modules. Moreover, poly-EA acts as a protective barrier against moisture and ion migration. Combined with improved DMSO removal, EA-modulated devices demonstrate a T80 lifetime of up to 1800 h under maximum power point tracking at 55–60% relative humidity in ambient air.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"22 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142940202","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}

Moreover, suspension-based photothermal-assisted catalysis presents further challenges, particularly concerning formation of heterojunctions between photocatalysts and photothermal materials that disrupt charge-transfer pathways and are exacerbated by photothermal heating-induced carrier recombination. Here, a photocatalytic system is proposed in which three key photoprocesses: photothermal, photogeneration-charge separation, and photoredox are spatially decoupled yet coordinated, aimed at addressing prevalent challenges of photothermal-assisted catalysis and adsorption-mediated catalyst deactivation in harsh environments. Essentially, the proposed polymeric tandem photothermal catalytic (PTPC) film consists of TiO2/Au photocatalytic and CuS photothermal layers, spatially separated and encapsulated by polymeric layers, which serve as spacer inhibitors to conflicting photochemical-photothermal pathways and corrosion-resistant redox medium. The PTPC film exhibits enhanced light absorption, mass transfer, and photothermal effect, surpassing traditional suspension catalysts and enabling interfacial redox reactions on the passive film surface. The PTPC system represents a new paradigm of polymeric film photocatalysis, enabling unimpeded photoredox-photothermal pathways and catalyst stability for application in hostile seawater and plastic waste environments. Such a paradigm can be used to develop localized, onsite solutions for photothermal H2 production that minimize logistical and environmental challenges.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"20 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142940281","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}

High adipic acid selectivity (>90%) in a wide potential window (from 0.3 to 1.3 V versus RHE) is achieved under ambient conditions based on TiO2 nanorods array photoanode modified with nickel hydroxide nanosheets (Ni(OH)2/TiO2). Experimental and theoretical data reveal that a new Ni2+δ─OH* reactive center with moderate oxidation capacity is in situ generated on Ni(OH)2/TiO2 photoanode under illumination, which abstracts H atoms from Cα─H bonds in CYC to obtain 2−hydroxycyclohexanone intermediate, and thereby facilitates subsequent C─C cleavage to produce adipic acid. Moreover, the PEC synthesis of adipic acid from industrial raw material of phenol is achieved by coupling cathodic phenol reduction to CYC and photoanodic CYC oxidation to adipic acid, demonstrating a new and sustainable approach for adipic acid synthesis by directly using solar energy.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"20 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142940203","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}

It focuses on transient absorption spectroscopy across multiple timescales and ultrafast time-resolved vibrational spectroscopy to acquire the “holy grail” of simultaneous structural and dynamic information for anti-PDFC and its blend with the well-known conjugated polymer PM6. Most significantly, it is observed that the singlet exciton of anti-PDFC is localised on the perylene diimide central core of the molecule, but the radical anion is primarily localised on the fluorinated indene malonitrile terminal units (which are common to many state-of-the-art non-fullerene acceptors, including the Y6 family). This electron transfer from the central core to the termini of an adjacent molecule is facilitated by a close interaction between the termini and the central core, as evidenced by single crystal diffraction data and excited state calculations. Finally, the very efficient charge extraction measured for PM6:anti-PDFC photovoltaic devices may be correlated with this anion localization, enabling effective charge transport channels and thus enhancing device performance.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"45 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142940201","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}
