However, industrial-scale co-precipitation presents significant challenges, particularly in maintaining particle sphericity, ensuring a stable concentration gradient, and preserving production yield when transitioning from lab-scale compositions. This study addresses a critical issue in the large-scale synthesis of nickel-rich NCM (<i>x</i> = 0.8381): nickel leaching, which compromises particle uniformity and battery performance. To mitigate this, we optimize the reaction process and develop an artificial intelligence-driven defect prediction system that enhances precursor stability. Our domain adaptation based machine learning model, which accounts for equipment wear and environmental variations, achieves a defect detection accuracy of 97.8% based on machine data and process conditions. By implementing this approach, we successfully scale up NCM precursor production to over 2 tons, achieving 83% capacity retention after 500 cycles at a 1C rate. In addition, the proposed approach demonstrates the formation of a concentration gradient in the composition and a high sphericity of 0.951 (±0.0796). This work provides new insights into the stable mass production of NCM precursors, ensuring both high yield and performance reliability.</p><p>\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":48538,"journal":{"name":"Infomat","volume":"7 7","pages":""},"PeriodicalIF":22.7,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inf2.70031","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144635378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The conversion of hydrogen energy through fuel cells has emerged as a central technology in this pursuit. Notably, protonic ceramic fuel cells (PCFCs) hold potential for the future hydrogen energy ecosystem, owing to their impressive energy conversion efficiencies at low-to-intermediate temperatures (300–750°C). It is becoming increasingly evident that the development of PCFC technology relies on advancements in the cathode, as oxygen-involved reactions often exhibit sluggish kinetics. In this comprehensive review, we aim to provide an overview of the current state of knowledge concerning the design of advanced cathodes for PCFCs. This includes discussing key descriptors for cathodes, methods for characterizing material properties, and functionalization techniques to enhance electrode performance.

Yet, the traditional solar cell manufacturing techniques, such as spin coating and screen printing, have significant limitations that seem to hinder the further development of solar cell technology. Compared with traditional manufacturing processes, additive manufacturing (AM) boasts advantages such as flexibility in the printing process, precise control over material deposition, and simpler procedures. These features provide a foundation for further enhancing solar cell performance and expanding their applications. This review outlines the superiority of AM compared with traditional solar cell manufacturing methods and highlights how AM has addressed specific challenges currently faced by solar cells. The most widely researched solar cell structures in recent years were briefly reviewed with summarizing their advantages and disadvantages. Then, a comprehensive overview of different manufacturing processes, including traditional printing methods and AM, is presented. Especially, their workflows, characteristics, and impressive innovative applications in solar cell manufacturing were discussed in detail. Finally, based on the current state of research, the review reflects on the future prospects of applying AM technology in space solar energy production, such as integrated printing with protective outer layers together with the solar cells, customized functional structure printing, flexible large-scale printing, and printing of high-performance novel materials with nanoscale and microscale structures.</p><p>\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":48538,"journal":{"name":"Infomat","volume":"7 7","pages":""},"PeriodicalIF":22.7,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inf2.70017","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144635379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Copper-silver-bismuth iodide (CABI) is a promising solar cell material with halide perovskite genes, possessing eco-friendly, element-rich, and cost-effective characteristics. The fabrication of high-quality CABI films with tailored compositions still poses a substantial hurdle. We developed a CuAgBi₂I₈ material that effectively reduced the bandgap to 1.69 eV by optimizing Bi distribution to create an environment conducive to in-situ redox reactions of Bi with I₂, Cu, and Ag via vapor-phase synthesis. This strategy proved highly effective in synthesizing high-quality CuAgBi₂I₈ compound, accompanied by significant improvements in film quality, including enhanced crystallinity, minimized defects, and reduced non-radiative recombination. The crystal structure of CuAgBi₂I₈ and mechanisms of elemental reactions and diffusion are discussed. Devices featuring the structure FTO/c-TiO₂/m-TiO₂/CuAgBi₂I₈/CuI/Spiro-OMeTAD/carbon achieved a champion efficiency of 3.21%, the highest for CABI solar cells.

Ferroelectric polymers are highly valued in soft robots for their flexibility, lightweight, and electrically controllable deformation. However, achieving large strains in ferroelectric polymers typically requires high driving voltages, posing a significant challenge for practical applications. In this study, we investigate the role of crystalline domain size in enhancing the electrostrain performance of the relaxor ferroelectric polymer poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene-fluorinated alkynes) (P(VDF-TrFE-CFE-FA)). Leveraging its remarkable inverse piezoelectric coefficient (|<i>d</i>₃₃*| = 701 pm V⁻¹), we demonstrate that the planar films exhibit a five times larger bending angle than that of commercial PVDF films at low electric fields. Based on this material, we design a petal-structured soft robot that achieves a curvature of up to 4.5 cm⁻¹ at a DC electric field of 30 V μm⁻¹. When integrated into a bipedal soft robot, it manifests outstanding electrostrain performance, achieving rapid locomotion of ~19 body lengths per second (BL s⁻¹) at 10 V μm⁻¹ (560 Hz). Moreover, the developed robot demonstrates remarkable abilities in climbing slopes and carrying heavy loads. These findings open new avenues for developing low-voltage-driven soft robots with significant promise for practical applications.</p><p>\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":48538,"journal":{"name":"Infomat","volume":"7 6","pages":""},"PeriodicalIF":22.7,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inf2.70015","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144308720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is a key challenge in the realization of next-generation low-power and high-performance devices. While various methods exist for metallizing Mo- and W-based 2D semiconductors like MoS₂ and WSe₂, effective approaches for Pt-based ones have been lacking. This study demonstrates that platinum dichalcogenides (PtX₂, X = Se or Te) undergo a semiconductor-to-metal transition when grown on niobium dichalcogenides (NbX₂, X = Se or Te). PtX₂/NbX₂ heterostructures were fabricated using molecular beam epitaxy (MBE) and characterized by Raman spectra, scanning transmission electron microscopy (STEM) and scanning tunneling microscopy/spectroscopy (STM/STS). Raman spectra and STEM confirm the growth of 1T-phase PtX₂ and 1H-phase NbX₂. Both 2D STS mapping and layer-dependent STS show that regardless of their layer numbers, both pristine semiconducting PtSe₂ and PtTe₂ are converted to metallic forms when interfacing with NbSe₂ or NbTe₂. Density functional theory (DFT) calculations suggest that the metallization of PtSe₂ on NbX₂ and PtTe₂ on NbTe₂ results from interfacial orbital hybridization, while for PtTe₂ on NbSe₂, it is due to the strong <i>p</i>-doping effect caused by interfacial charge transfer. Our work provides an effective method for metallizing PtX₂ semiconductors, which may lead to significant applications such as reducing the contact resistance at metal electrode/2D semiconductor interfaces and developing devices like rectifiers, rectenna, and photodetectors based on 2D Schottky diodes.</p><p>\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":48538,"journal":{"name":"Infomat","volume":"7 6","pages":""},"PeriodicalIF":22.7,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inf2.70010","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
