Thermodynamic theory reveals the impact of surface and interface energies on the equilibrium properties and solubility limits of interstitial ions in nanosized crystallites. Applied to Li x FePO 4 especially interface energy contributions play important roles, and their effect explains observations of the narrowing of electrochemically measured miscibility gaps in nanostructured electrodes.
