The best catalysts reported to date often require laborious fabrication methods and controlled environments to fabricate the catalysts or high temperatures and long times to activate the catalysts. This work introduces a facile one-pot method to fabricate carbon (C)-based, barium (Ba)-promoted cobalt (Co) catalysts via the citric acid sol–gel method with metal nitrates as precursors and water as the solvent. This approach ensures the homogeneous incorporation of metal ions into the carbon framework. The resulting (Ba/Co)0.3/C catalyst demonstrates an outstanding NH3 synthesis activity of 34 mmol gcat−1 h−1 (350 °C, 1.0 MPa) with excellent stability. In-depth characterizations reveal that Ba exists as barium oxide (BaO), uniformly distributed on the carbon framework and around the Co nanoparticles. It is uncovered that retarding barium carbonate (BaCO3) formation in the fresh catalyst significantly reduces the reduction temperature and time (485 °C/4 h), which is a fundamental advantage of this method. Density functional theory and molecular dynamics simulations indeed support the experimental observations. It is anticipated that this simple and economical strategy will resolve the issues in a broad field of heterogeneous catalyst research.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"37 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142804715","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}

The dual mechanisms of surface oxygen evolution due to anion redox and anisotropic volume change upon delithiation synergistically pulverize and degrade the material. Detailed Density Functional Theory (DFT) modeling and analysis of the anisotropic structural changes associated with crack formation in LiNiO2 (LNO) reveals the link of mechanical behavior to charge transfer and oxygen redox activity upon deep charge cycling (>4.2 V vs Li/Li+). In the two-phase region and H2–H3 transition from 66% to 100% delithiation, oxygen of [NiO6] octahedra is discovered to undergo redox in growing the Li-deficient regions, causing c-lattice mechanical weakening and collapse as the Li-slab becomes depleted. Li-site dopants are investigated to locally compensate against anion redox, resulting in enhanced coulombic repulsion and supporting the interslab layer thickness even at 100% depth of charge. Ionic size and oxidation state of M in Lix-yMyNiO2 are found to fundamentally impact stabilization capability, moderating the anisotropic strain and volume expansion asynchronously. Optimization of mixed doping composition may then enable “zero strain” high-Ni Li(Ni,Co,Mn)O2 (NCM) or LNO.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"13 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142804716","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}

Unfavorable singlet and triplet energy surfaces in the solid state have limited the successful implementation of many conventional solution-based annihilators. To date, rubrene is still the best-performing annihilator; however, this comes at the cost of a limited apparent anti-Stokes shift. To this point, anthracene derivatives are promising candidates to increase the apparent anti-Stokes shift. The well-known green glowstick dye 9,10-(bisphenylethynyl)anthracene (BPEA) and its chlorinated derivatives have already shown promise in solution-based UC applications. Due to favorable band alignment of the perovskite and triplet energy levels of BPEA, it is conceivable that a wide variety of BPEA derivatives can be compatible with the perovskite-based UC system. Here, the properties of the parent molecule BPEA and its derivatives 1-chloro-9,10-(bisphenylethynyl)anthracene and 2-chloro-9,10-(bisphenylethynyl)anthracene are investigated. Despite similar optical properties in solution, the different molecules exhibit vastly different properties in thin films.

Initially, ML algorithms were successfully applied to screen materials databases by establishing complex relationships between atomic structures and their resulting properties, thus accelerating the identification of candidates with desirable properties. Recently, the development of highly accurate ML interatomic potentials and generative models has not only improved the robust prediction of physical properties, but also significantly accelerated the discovery of materials. In the past couple of years, ML methods have enabled high-precision first-principles predictions of electronic and optical properties for large systems, providing unprecedented opportunities in materials science. Furthermore, ML-assisted microstructure reconstruction and physics-informed solutions for partial differential equations have facilitated the understanding of microstructure–property relationships. Most recently, the seamless integration of various ML platforms has led to the emergence of autonomous laboratories that combine quantum mechanical calculations, large language models, and experimental validations, fundamentally transforming the traditional approach to novel materials synthesis. While highlighting the aforementioned recent advances, existing challenges are also discussed. Ultimately, ML is expected to fully integrate atomic-scale simulations, reverse engineering, process optimization, and device fabrication, empowering autonomous and generative energy system design.

In fact, the presence of conductive carbon in the cathode, necessary for high capacity and power capability, is believed to aggravate the stability woes. Thus, it is typically excluded from the cathode mix. Herein, employing a model functionalized carbon, it is shown that a small carbon surface oxygen functionality can in situ engineer a robust carbon–solid electrolyte interphase, which arrests conductive carbon-mediated degradation of Li6PS5Cl into reactive polysulfides that degrades the active LiNi1/3Mn1/3Co1/3O2 (NMC) cathode. Such interfacial stabilization, as confirmed by ex situ spectroscopic and in situ impedance analysis, combined with fast charge transport facilitated by functionalized yet conductive carbon and lowly resistive cathode interphases, elevates the performance. This is evidenced by stable cycling at room temperature (22 °C) and elevated temperatures (60 °C), high rate capability, a Coulombic efficiency of 99.8%, and ≈100% capacity retention after 1000 cycles and >90% retention over 2000 cycles at 60 °C. Functionalized carbon-mediated in situ cathode interfacial engineering offers a simple and scalable approach to designing durable ASSLB cathodes, with the potential for broader application across various NMC cathodes and compatible solid electrolytes.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"24 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142804965","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}

To address the challenges associated with fabric substrate system fabrication and encapsulation, a printing-cutting-transfer technology is proposed. This method enables the creation of unique, low-cost, high-precision, and robust circuit routing and electronic devices on fabric, maintaining high compatibility with commercial surface mounting technology while minimizing sacrifices in breathability. Additionally, a backscatter communication mechanism is designed and implemented to achieve wireless data transmission, which significantly reduces power consumption. Combined with energy management technology and hydrogel batteries, the SBBMS receives safe, multi-source, and eco-friendly energy support. Furthermore, through meticulous design, all modules—including the antenna, circuit, and battery—are made stretchable, providing the system with excellent strain-resistive performance.

Hetero-structured catalysts may improve surface adsorption through extensive interfacing between phases, enabling active transportation of reaction intermediates.
