Experiments, numerical simulations, and analytical calculations are used tocalibrate a diffuse-interface Cahn-Hilliard model of Li-Sn thin film electrodesthat experience a transformation from Sn to Li2Sn5. It is shown that aconcentration-gradient dependent mobility can be used in the Cahn-Hilliardequation to give the interface a finite mobility and capture its nonequilibriumbehavior. Comparing experiments and simulations, the free-energy of Li-Sn,diffusivity of Li in Sn and Li2Sn5, the exchange current density for thesurface reaction, and the mobility of the Sn/Li2Sn5 interface are extracted.The implications of finite interface mobility for practical battery electrodesare discussed.
