Accuracy of simulated LFP battery characteristics, including the cell voltage, lithium concentration distribution, and cell capacity, are highly related to the solid-phase initial concentrations of each individual electrode. To determine the initial concentrations of individual electrodes of the LFP battery, equilibrium potentials are experimentally measured by low-rate discharge while the characteristic points are calculated by identifying critical points of the discharge curves. The LFP battery model with such formally determined concentrations is validated by comparing the simulated discharge curves with experimental measurements under various loading demands. Further understanding of the effects of lithium loss during activation process with experiments and model simulation can assist the LFP battery design and optimize fabrication. © The Electrochemical Society.
