Here, Q loss is the capacity loss, T is the absolute temperature in Kelvin, C is the discharge rate, n is the cycle number, A(C) is the pre-exponential factor, and E a (C) is the activation energy. Omar et al. 16 also reported an exponential influence of discharge rate on the cycle life of the cylindrical 2.3 Ah LiFePO 4 /graphite lithium-ion cells.
Fig. 1 d performed the discharge curves of the batteries storage at 45 C with different aging times. There was no significant change of discharge curves except for the capacity compared with the initial discharge curve. While for the IC and DV curves (Fig. 1 e and f), the corresponding feature peaks had some degree of variation.
