The capacity of all three groups of Li-ion batteries decayed by more than 20%, and when the SOH of Li-ion batteries was below 80%, they reached the standard of retired batteries.
Thiringer et al. showed that avoiding cycling lithium-ion batteries in the high SOC ranges could effectively prolong battery life. Saxena et al. demonstrated that the capacity decline rate of the LiCoO 2 pouch battery increased with an increase in SOC swing ranges.
The degradation mechanism of lithium-ion batteries is complex and the main cause of performance degradation of lithium-ion batteries at low temperatures is lithium plating. During charging, lithium ions migrate from the cathode to the anode and become entrapped in the graphite layer.
For lithium-ion batteries, multiple external stress factors such as ambient temperature, depth of discharge (DOD), state of charge (SOC) swing range and charging/discharging rate, etc., have a great impact on the electrochemical evolution of different aging mechanisms.
Furthermore, the rate of lithium plating was significantly faster in the ranges of [35–85%] and [45–95%] compared to the other three ranges, resulting in a significant difference in the rate of the battery capacity decline (Figure 3). It can be noted that the growth of the SEI layer and lithium plating resulted in a decrease in porosity.
Higher charging and discharging rates accelerate the aging process of LIBs, with the charging rate serving as the decisive factor in the degree of aging. The ohmic internal resistance of lithium-ion batteries exhibits a pattern of initial decrease followed by an increase during cyclic aging in a low-temperature environment.
