It was also observed that the low temperature caused the uniformity of the battery to deteriorate as a result of temperature and voltage differences, and the uniformity became poorer with increasing cycle rate. Moreover, the capacity decay rate of the battery was demonstrated to be greatly accelerated by the low temperature.
Until now, much work has been done to probe the influence of low temperature on LIBs. 6–12 Ling et al.6 cycled batteries under ambient temperatures of −10 and 5 °C, respectively; their results showed that the low temperature environment harmed the battery performance, reducing the discharging voltage and accelerating the capacity decay.
The high temperature effects will also lead to the performance degradation of the batteries, including the loss of capacity and power , , , .
Based on the experimental results, it was found that the battery exhibited a higher temperature increase at low ambient temperature due to the larger internal resistance of the battery at low temperature, which resulted in greater heat generation.
It can be obviously seen that the IM had a significant effect on warming the batteries up. Under the effect of the IM, the rate of surface temperature increase of the battery was greater than that in the absence of the IM, and therefore, a higher surface temperature was observed.
