As the batteries are fully charged, the OCV is immediately dominated by the relaxation caused by diffusion and charge-transfer dynamics, while the voltage decrease is significantly slower than the relaxation of the overpotential from the charging process [4, 35]. It agrees with the observation that a rapid voltage drop occurred at the first 24 h.
In a low-temperature environment, the battery’s internal polarization resistance is higher, leading to a large amount of heat generation during high-rate discharge, which enhances the battery’s internal activity and causes the voltage to rise. However, the amount of power that can be discharged in a low-temperature environment is reduced.
Storage induces two forms of losses: Self-discharge that can be refilled with charging before use, and non-recoverable losses that permanently lower the capacity. Table 2 illustrates the remaining capacities of lithium- and nickel-based batteries after one year of storage at various temperatures.
During rapid discharge at a 3 C rate in low-temperature conditions, the initial voltage reduction of the battery becomes increasingly noticeable with increased aging. Due to this significant voltage drop, if the voltage falls below 2.50 V, the battery struggles to complete the discharge.
At the 150th charging cycle, the charging voltage plateau of the LIB increases overall, indicating that the polarization phenomenon in the aging battery is more obvious, and the batteries cycling under −10 and −20 °C can only be charged at a constant voltage.
In a −20 °C environment, with a discharge rate of 0.33~0.50 C, the larger the rate, the slower the relative capacity degradation. This phenomenon may be due to enhanced battery activity from internal heat generation when charging at a low rate.
