“…Hongfei Wu et al selected the commercial 18650 Lithium iron phosphate battery to study its electrothermal performance, and established different temperatures, different discharge currents and different Depth of Discharge (DOD). The predicted temperature changes are very similar to the experimental results [9] . P. Nie, et al proposed an electrochemical thermal coupling model and conducted a temperature health analysis on the charge-discharge cycle of lithium-ion batteries.…”

“…It is found that the charge-transfer resistance is the primary reason for the cell power decline under low temperature. Wu 26 studied the effects of different temperatures and discharge currents on the electrical-thermal behaviors of lithium-ion batteries. It was found that reducing the activity of lithium ions and the amount of available active materials and increasing the electrical resistance will cause cell performance degradation under low-temperature conditions.…”

Low-temperature high-rate cycling leads to accelerated performance degradation of lithium-ion batteries, which seriously hampers the large-scale popularization of electric vehicles. To clarify the battery degradation characteristics and mechanisms, this work conducts an in-depth investigation on the commercial lithium-ion batteries with 37 A h during the long-term cycling under low-temperature high-rate charging. The battery capacity displays the decelerating degradation trend during the long-term cycling, and the battery capacity recovery rate is as high as 80−90%. Furthermore, it is interesting that the constant current discharge capacity exhibits jumping behavior at around 120th cycle during the discharge process. By postmortem characterization analysis, it is found that lithium plating is the primary degradation mechanism. Lithium plating exhibits nonuniformity and displays a decelerating trend in the later stage. In view of the lower temperature, the plated lithium can better retain the reaction activity, which results in a higher capacity recovery rate. Besides, lithium plating increases the internal polarization, which makes the constant current discharge capacity jump when lithium plating reaches a certain level. The findings can provide certain references for battery optimization.

“…In the other range from 25°C to 70°C, the ageing rate increases with an increase in temperature from its nominal operable value. The influence of low ambient temperatures on lithium-ion battery performance was examined in [1,15], where a drop in activity and amount of useable active material, as well as an increase in resistance, resulted in a decrease in operating voltage and energy supplied. The performance of batteries at higher temperatures of 26°C and 70°C has been investigated in [9] and it is observed that the charging capability of the batteries at 70°C is relatively higher than that of the 26°C.…”

Lithium-ion batteries suffer from insufficient electrical performance due to the unpredictable thermal effect and dynamic behaviour during the charging and discharging process. However, the comprehensive impact of relative humidity (RH) on the charging process rate has yet to be investigated. In this paper, a set of experimental tests is implemented to investigate the charging and discharging thermal and electrical behaviour of lithium-ion batteries represented by a single-cell 1000 mAh and battery pack 2200 mAh. The charging process is employed using the constant current-constant voltage (CC-CV) protocol, according to the safety specifications of the manufacturer. The proposed scenarios applied in this paper are initiated by investigating the behaviour of the charging current, total interval time, and battery terminal voltage whilst varying the ambient temperature between 30°C and 40°C at a fixed RH of 52%. Then a set of experiments are conducted by changing the RH conditions (35%, 52%, and 70%) at a fixed ambient temperature of 40°C. Finally, the impact of changing the RH at a fixed ambient temperature during the charging process is scrutinized. The results of the investigations of lithium-ion battery charging behaviour reveal that charging at low RH ensures the fastest charging rate response using the CC-CV protocol. At low RH (35%) the charging interval time is reduced by almost 23% corresponding to high RH (70%).
