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.
Low rates and high temperatures make the polarization of LIB less. However, it can slowly reach the cut-off voltage at the end of discharge process for a long time, so the relatively long end of discharge makes the battery stay in the temperature rise stage for a longer time.
The accumulation of lithium at low temperatures is a result of the slow movement of Li + into and within the negative electrode's host matrix [30, . ... ...
It falls off from the current collector, which reveals that more lithium evolution leads to higher thermal runaway temperatures and more severe carbonization. Fig. 12. The mass loss, mass loss rate in the process of TR a), pictures of the batteries after thermal runaway b) and picture of the batteries after disassembly.
At these low operating temperatures, LIBs will show slow chemical-reaction activity and charge-transfer velocity , which leads to the decrease of ionic conductivity in the electrolytes and lithium-ion diffusivity within the electrodes .
