| Abstract Scope |
High-entropy materials (HEMs) initially emerged as promising candidates for structural applications, exemplified by the extensively studied high-entropy alloys. Recently, the application of HEMs expanded into broader fields, including energy storage and conversion. We will demonstrate the potential of these materials as high-performance, low-cost materials for battery electrode/electrolytes and electrocatalysis. To facilitate rapid discovery of synthesizable and high-performance compositions and structures, we developed a specialized database containing over 200,000 DFT-computed high-entropy alloys and metal oxides. Furthermore, we will illustrate how integrating physical models with advanced deep learning algorithms enables the development of a universal stability predictor to assess the synthetic accessibility of these materials. Finally, we will present case studies that delve into unique phenomena, including enhanced diffusivity and compositional dependent corrosion resistance in HEMs. |
