Transition metal oxides (TMOs) have attracted great attention as high capacity anode materials because they can store multiple lithium ions (electrons) per unit formula via conversion reaction, resulting in high specific capacity (700-1,200 mAh g-1) and volumetric capacity (4,000-5,500 mAh cm-3). In addition, TMOs are cheap, earth-abundant, non-toxic and environmentally friendly. However, there have been no reports of practical LIBs using conversion-based TMO anodes, because of several major problems such as large voltage hysteresis, low initial Coulombic efficiency (large initial capacity loss), low electrical conductivity, and large volume changes (100~200%). This review summarizes the recent progress, challenges and opportunities for TMO anode materials. The conversion reaction mechanism, problems and solutions of TMO anode materials are discussed. Considering iron oxide as a promising candidate, future research directions and prospects for the practical use of TMO for LIB are presented.","PeriodicalId":9738,"journal":{"name":"Ceramist","volume":"51 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76050655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, the current state-of-the-art catalysts still suffer from high cost of noble metals, insufficient catalytic activity and long-term stability. Furthermore, the current strategy to develop new catalysts relies on “trial-and-error” method, which could be time-consuming and inefficient. To tackle this challenge, atomic-level simulations have demonstrated the potential to facilitate catalyst discovery. For the past decades, the simulations have become reasonably accurate so that they can provide useful insights toward the origin of experimentally observed improvements in catalytic properties. In addition, with the exponential increase in computing power, high-throughput catalyst screening has become feasible. More excitingly, recent advances in machine learning have opened the possibility to further accelerate catalyst discovery. Herein, we introduce recent applications and challenges of computation and machine learning for catalyst discovery.","PeriodicalId":9738,"journal":{"name":"Ceramist","volume":"57 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89110150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A surge of attention originates from unprecedentedly rapid enhancement in power conversion efficiency (PCE) to reach over 25%, being competitive with commercialized silicon solar cells. The charge transporting layer, in particular, an electron transport layer (ETL) is one of the key components for high-performance PSCs. The ETL affords efficient extraction of the photo-generated electrons from the perovskite layer, which are subsequently transferred to transparent conduct oxide electrode. Tin oxide (SnO2) is one of the most attractive materials for the ETL due to its wide band gap, high optical transmission, high carrier mobility and high chemical stability. Moreover, the facile low temperature deposition process of SnO2 layer is suitable for mass production as well as versatile applications such as flexible devices. Regardless of excellent intrinsic properties, however, quality of the functional layer and resulting device performance is largely affected by the fabrication process of the material. In this study, we review the studies to utilize the SnO2 ETL for PSCs by adopting various fabrication processes, ultimately to improve efficiency and stability of the PSCs.","PeriodicalId":9738,"journal":{"name":"Ceramist","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74179632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To avoid the kerf-loss, direct growth of crystalline silicon wafers of 50-150 μm with a porous separation layer that can be mechanically broken during the exfoliation process, has been widely investigated. However, several issues including flattening of the surface after the exfoliation remain unsolved. In this work an alternative method that utilizes a water-soluble Sr3Al2O6 (SAO) sacrificial layer inserted between the mother substrate and the grown crystalline silicon layers is introduced. Polycrystalline silicon layers were grown on SAO/Si by plasma-enhanced CVD process and silicon membranes could be successfully obtained after the dissolution of SAO in the water. Same process could be applied to obtain flexible amorphous silicon membranes. Further research is being conducted to increase the size of the exfoliated wafer, which expects to reduce the production cost of crystalline silicon solar cells effectively.","PeriodicalId":9738,"journal":{"name":"Ceramist","volume":"53 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90976129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
