Previous analyses have predominantly focused on the electrochemical reaction mechanism of lithium -ion battery low-temperature. However, there is still a lack of effective algorithms for the discharge capacity evaluation of lithium batteries at low temperatures.
In terms of discharge, the capacity of the battery decreases exponentially with the decreasing temperature. The EIS shows that the ohmic internal resistance and charge transfer impedance of the battery increase as the temperature decreases, and the diffusion process slows down.
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.
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.
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.
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 .
