Current density and state of charge inhomogeneities in Li-ion battery cells with LiFePO4 as cathode material due to temperature gradients

► Operated Li-ion cells develop a temperature gradient inside the electrode stacks. ► Current density inhomogeneities occur in Li-ion cells due to temperature gradients. ► SoC inhomogeneities occur in operated LiFePO4-cells due to temperature gradients. ► SoC inhomogeneities persist in operated LiFePO4-cells even during relaxation.
