How are the materials in the battery explorer chosen? i.e., an unlithiated phase with some energy above hull usually forms the starting point for the battery cycle, but you can find a lot of different phases with the same elemental composition. Was there a methodology for choosing the materials that went into the Battery Explorer?
Intercalation battery materials are matched by structure to make sure the unlithiated and lithiated phases has the same host structures. For example, Li0.25CoO2 and LiCoO2 should have the same CoO2 structural framework (https://materialsproject.org/batteries/mp-300024850/).
