摘要： The kagome lattice, characterized by a hexagonal arrangement of corner-sharing equilateral triangles, has garnered significant attention as a fascinating quantum material system that hosts exotic magnetic and electronic properties. The identification and characterization of this class of materials are critical for advancing our understanding of their role in emergent phenomena such as superconductivity. In this study, we developed a high-throughput screening framework for the systematic identification and classification of superconducting materials with kagome lattices, integrating them into established materials databases. Leveraging the Materials Project (MP) database and the MDR SuperCon dataset, we analyzed over 150000 inorganic compounds and cross-referenced 26000 known superconductors. Using geometry-based structural modeling and experimental validation, we identified 129 kagome superconductors belonging to 17 distinct structural families, many of which had not previously been recognized as kagome systems. The materials are further classified into three categories in terms of topological flat bands, clean band structures, and coexisting magnetic or charge density wave (CDW) orderings. Based on these results, we established a database comprising 129 kagome superconductors, including the detailed crystallographic, electronic, and superconducting properties of these materials.
