The thermodynamic interpretation of the phenomenon also clarifies why solid solution materials cannot experience a kinetically induced memory effect. As the electrochemical model demonstrates (Fig. ), the combination of Fickian diffusion and monotonic chemical potential of solid solution materials impose a fast relaxation of the system: the single particle is rapidly homogenized by internal diffusion, and the difference between the surface concentrations, induced by the previous fast kinetics, drives an inter-particle reaction that quickly homogenizes the system. In phase-separating materials, instead, once the particle is nucleated, both phases will be characterized by similar chemical potentials, and the driving force for multi-particle equilibration is strongly reduced. The origin of this kinetic response is also shown to be general and reproducible in other phase-separating materials as shown by the simulation performed with the Li4Ti5O12 model (Fig. ).
