High-entropy materials offer a huge research area for new material compositions and potential applications, e.g. in the field of rechargeable batteries, electrochemical catalysis, hydrogen storage or supercapacitors.[1] In particular, the combinatorial complexity of several elements in a single-phase structure, can lead to unexpected and unpredictable material properties, which may affect potential application areas. Exploring the vast compositional space of high-entropy materials in a conventional approach, i.e., one experiment at a time is prohibitive in terms of cost and time. Consequently, the development of high-throughput experimental methods supported by machine learning and theoretical predictions will facilitate the search for multicomponent materials in their compositional diversity.<br/>Therefore, this talk will focus on the establishment of automated high-throughput methodologies in the field of synthesis and characterization of metallic and non-metallic (ceramic) high-entropy materials, enabling the creation of material libraries.[2,3] This facilitates the analysis of material properties in terms of composition or morphological and structural differences. Machine learning-based data analysis and theoretical approaches also provide opportunities for the virtual development of novel materials for both functional and structural applications.<br/><br/><br/>1.
