Scaling factor β [see Eq. (36)] of time dependence of SEI growth as a function of OCV and SEI thickness according to Equation (22). Red indicates reaction limitation [Eq. (23), β=1] or migration limitation during charging [Eq. (27a), β=1]. Yellow indicates diffusion limitation [Eq. (25), β=0.5] and green migration limitation [Eq. (27b), β=0). (a) Battery storage. (b) Battery charging with j=−0.2 C in the short‐term evaluation. (c) Battery charging and (d) battery discharging with j=−0.2 C in the long‐term evaluation.
