data & code

Dataset and code available

Dr. Ouyang is interested in developing theory, model and simulation tools to understand the energy landscape of inorganic solids. \ The method/code/dataset developed by Dr. Ouyuang’s group includes:

MAX based Al-ion battery electrode dataset

We developed a computational dataset with 425 Ternary MAX materials that can potentially be intercalation host of Al-ion battery. Phase diagrams, diffusion barriers and other predicted electrochemical performance of these materials are available at Github.
