This dataset complements the publication Thermodynamics and Kinetics of Li at the Ag-Li Battery Interface. In this project, we calculate thermodynamic properties for 6 different interfaces: KS, NW, Bain, Pitsch, FCC (111), and FCC (100). For all six interfaces, this dataset contains the per atom energies and vacancy formation energies for every atom calculated using the MACE-MP-0 pretrained potential. Also included are the MACE-MP-0 surface energies of each Ag and Li slab and MACE-MP-0 interfacial energies. For the two FCC surfaces, this dataset also contains DFT calculations for the surface and interfacial energies. Additionally, for the FCC surfaces, we include calculated migration barriers for vacancies across the Ag-Li interface using MACE-MP-0.
