In addition to studying the performance of batteries at low temperatures, researchers have also investigated the low-temperature models of batteries. The accuracy of LIB models directly affects battery state estimation, performance prediction, safety warning, and other functions.
To understand the charging performance changes of LIBs at low temperatures, we collected the data reported in the literature, as shown in Table 4, which lists the quantified capacity drop and the increased mid-point voltage (nominal and charging capacity) of different batteries under different conditions.
Modern technologies used in the sea, the poles, or aerospace require reliable batteries with outstanding performance at temperatures below zero degrees. However, commercially available lithium-ion batteries (LIBs) show significant performance degradation under low-temperature (LT) conditions.
In terms of degradation, the degradation of the battery at low temperature is more serious than at room temperature, and the maximum degradation rate can be 47 times that of room temperature, which increases exponentially as the temperature decreases.
Conclusions and perspectives. Firstly, the performance of LIBs at low temperatures is summarized, including four perspectives: charging, discharging, EIS, and degradation. Charging at low temperatures results in lower charging capacity and higher midpoint voltage, reaching the endpoint voltage more quickly than at room temperature.
The internal resistance of the battery increases when the battery is cycled at low temperatures. The increase of the internal resistance will not only have a negative impact on the battery performances (capacity reduction and power fade) but also on the energy efficiency of the battery .
