examination, dimensional measurement, residual gas analysis to detect any leakage, electrical tests to appraise the electrical performance, and X-ray computed microtomography to view the cell internal features were carried out prior to and after soaking. It has been concluded that the tested cells demonstrated successful survivability without any internal damage or electrical performance degradation. In 2019, Grandjean et al. at University of Warwick investigated the effect of flash cryogenic freezing on the electrical performance of commercial lithium-ion batteries. [2] Two different cell formats, i.e., nickel manganese cobalt oxide pouch cells and nickel cobalt aluminum oxide cylindrical cells, each with different states of charge, were soaked at 77 K for a duration of five minutes and then allowed to return to room temperature. Each cell went through five such cycles. Cell impedance and capacity were characterized after each cycle. It has been concluded that very little detrimental impact on cell performance was found after five freeze-thaw cycles. In another study, they investigated the effect of flash freezing on battery lifetime and aging. [3] On the cells that were flash frozen and the control groups, cell impedance and capacity were measured at regular intervals during cycling. It has been concluded that flash cryogenic freezing did not affect battery lifetime and aging.In 2021, the study conducted by Li et al. revealed the irrevocable performance deterioration of lithium-ion batteries as a result of exposure to low-temperature conditions. [4] They first cycled the lithium-ion cells at room temperature for 20 cycles and then paused the cycling procedure at the discharged state. They stored the cells at four different temperatures, i.e., room temperature, -20 °C, -40 °C, and -80 °C, for 48 h and then brought them back to room temperature to store for another 48 h. Subsequently, they resumed the electrochemical cycling to monitor the impact of low-temperature storage on battery performance. They performed these experiments at two different charging rates and concluded that the electrochemical performance of the cells was compromised after the low-temperature storage regardless of the charging rates.It can be seen that the effect of low-temperature exposure on the electrochemical performance of lithium-ion batteries is still a controversial issue. The study conducted by Li et al. is the first and the only study so far that reported the irrevocable performance deterioration as a result of cell exposure to lowtemperature conditions, calling for in-depth investigations on the low-temperature effect on structural integrity of lithium-ion batteries.
