Furthermore, a scalable transfer technique, in which CVD-grown few-layered graphene thin film is used as a sacrificial layer, is developed for transferring HZO-based ferroelectric stack pre-fabricated on SiO2/Si substrate onto a flexible polyimide (PI) membrane, with marginal loss in the ferroelectric properties of HZO. Importantly, mechanical bending testing demonstrates excellent flexibility of TiN/WOx/HZO/WOx/TiN stack, with robust polarization and superb endurance properties being well-maintained even after 104 cycles at a small bending radius of 2 mm. Both implementing ultrathin WOx as interfacial layers and utilizing two-dimensional materials assisted transfer technique would be of great value in the development of HfO2-based flexible ferroelectric memory.","PeriodicalId":16173,"journal":{"name":"Journal of Materiomics","volume":null,"pages":null},"PeriodicalIF":9.4,"publicationDate":"2024-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142374061","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 silicon-based anode materials have triggered global research interest due to low operating voltage and high specific capacity. However, for the Si-based anode, the large volume change during cycling causes cracking and pulverization of Si particles, leading to the sluggish kinetics and poor cycle life. In this work, fluoroethylene carbonate (FEC) and lithium bis(fluorosulfonyl)imide (LiFSI) are used as synergistic functional additives to enhance the performance of silicon–carbon (Si–C) composite anode in pouch cell. The properties of solid electrolyte interphase (SEI) formed on the surface of Si–C composite anode have been systematically investigated. The images of different electrolytes infiltration and gas production after formation are analyzed with ultrasonic transmission scanning technique. DFT calculations are used to illustrate the mechanism. All date collection is at pouch cell level, which is more persuasive.","PeriodicalId":16173,"journal":{"name":"Journal of Materiomics","volume":null,"pages":null},"PeriodicalIF":9.4,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142360660","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}

Fortunately, mollusk shells in nature have evolved effective strategies to construct microstructures with superior erosion and impact resistance. Inspired by the structure of nacre, Ag<img>SnO2 contact material with hierarchical architectures has been designed and fabricated. The mechanistic link between microstructural evolution and dynamic erosion is studied through experiments combined with Computational Fluid Dynamics (CFD) and Finite Element Method (FEM) simulations. Results show that the reconstructed SnO2 skeleton endowed with a highly continuous and anisotropic ‘flowering'-like structure forms a continuous interpenetrating network with Ag, optimizing the conductive pathways on the molten pool surface. Additionally, the Ag-rich regions in the deeper layers on both sides of the molten pool offers a stable ‘nutrient-supply’ for the continuous ‘flowering’ reconstruction of the skeleton, exhibiting excellent in-situ self-repairing erosion resistance. Benefiting from this synergistic strategy, this skeleton is reconstructed based on its natural structure, which further disperses the stress and deformation concentration while inhibiting interfacial debonding, thereby reducing the formation of cracks and significantly enhancing the impact resistance. This work is expected to breakthrough erosion and impact resistance in extreme condition electrical contact materials through biomimetic microstructure design.</div>","PeriodicalId":16173,"journal":{"name":"Journal of Materiomics","volume":null,"pages":null},"PeriodicalIF":8.4,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2352847824001539/pdfft?md5=a9f3f7b77387fea340e0fd458fe17baa&pid=1-s2.0-S2352847824001539-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141838871","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}
