“…Initially, three charge/discharge cycles are executed at 25 • C to stabilize the initial capacity of the batteries prior to the deterioration study. Charging is conducted, employing the constant current-constant voltage (CC-CV) method, initially at a rate of 0.3 C, which then transitions to a constant voltage (CV) phase with a termination current set at 150 mA [2,13]. Discharging is carried out at a constant current (CC) of 0.3 C, with the process halted when the voltage reaches 2.5 V. The HPPC curve is measured at 25 • C before and after deterioration (Table 2).…”

“…The lithium deposition rate is non-linearly correlated with the charging rate, and the reversible conversion rate of deposited lithium back into LIBs is independent of the amount deposited (Table 6, Figures 4A and 5A) [11,13,19]. At a charging rate of 0.25 C to 0.66 C at −20 • C, the relative capacity decreases more rapidly with an increasing rate.…”

Typical usage scenarios for energy storage and electric vehicles (EVs) require lithium-ion batteries (LIBs) to operate under extreme conditions, including varying temperatures, high charge/discharge rates, and various depths of charge and discharge, while also fulfilling vehicle-to-grid (V2G) interaction requirements. This study empirically investigates the impact of ambient temperature, charge/discharge rate, and charge/discharge cut-off voltage on the capacity degradation rate and internal resistance growth of 18,650 commercial LIBs. The charge/discharge rate was found to have the most significant influence on these parameters, particularly the charging rate. These insights contribute to a better understanding of the risks associated with low-temperature aging and can aid in the prevention or mitigation of safety incidents.

“…In addition, to prevent the occurrence of internal short circuits, the temperature distribution of BTMSs should be relatively uniform; i.e., the maximum temperature difference inside the battery should not exceed 5 • C [7]. Furthermore, 25 • C to 35 • C has been proved to be the optimal operating temperature range for lithium-ion batteries, resulting in the highest electrochemical efficiency and the lowest aging rate [8]. Other studies also show that when the battery pack works at 30 • C to 40 • C, battery life will be reduced by about 60 days for each degree of increase [9].…”

Batteries with high energy density are packed into compact groups to solve the range anxiety of new-energy vehicles, which brings greater workload and insecurity, risking thermal runaway in harsh conditions. To improve the battery thermal performance under high ambient temperature and discharge rate, a battery thermal management system (BTMS) based on honeycomb-structured liquid cooling and phase change materials (PCM) is innovatively proposed. In this paper, the thermal characteristics of INR18650/25P battery are studied theoretically and experimentally. Moreover, the influence of structure, material and operating parameters are studied based on verifying the simplified BTMS model. The results show that the counterflow, honeycomb structure of six cooling tubes and fins, 12% expanded graphite mass fraction and 25 mm battery spacing give a better battery thermal performance with high group efficiency. The maximum temperature and temperature difference in the battery in the optimal BTMS are 45.71 °C and 4.4 °C at the 40 °C environment/coolant, as against 30.4 °C and 4.97 °C at the 23.6 °C environment/coolant, respectively. Precooling the coolant can further reduce the maximum battery temperature in high temperature environments, and the precooling temperature difference within 5 °C could meet the uniformity requirements. Furthermore, this study can provide guidance for the design and optimization of BTMS under harsh conditions.
