Suppression of Phase Separation in LiFePO 4 Nanoparticles During Battery Discharge

Using a novel electrochemical phase-field model, we question the common belief that LiXFePO₄ nanoparticles always separate into Li-rich and Li-poor phases during battery discharge. For small currents, spinodal decomposition or nucleation leads to moving phase boundaries. Above a critical current den...
