Orendorff et al., in their study, pointed out that temperature variance between the cells in the larger battery packs is very high when compared to that of smaller battery packs. This uneven temperature profile will cause heterogeneous degradation of separators, which in turn causes uneven cell resistances within the battery pack. More research must be carried out in this area.
On the other side, when temperature decreases, the viscosity of liquid phase in quasi-solid-state batteries increases, leading to increased internal resistance both in the SE and interfaces. Such variation causes large overpotential and polarization, which will induce dendrite formation.
Slower Reactions: At low temperatures, the electrochemical reactions within a battery slow down significantly, leading to reduced capacity and power output. Cold Cranking Amps (CCA): For automotive batteries, CCA ratings indicate how well a battery can start an engine in cold conditions. Lower temperatures can result in a substantial drop in CCA.
The separator between the cathode and anode provides pathways for migration of Li-ions during charging and discharging. At high temperature, the separator shrinks and melts, which induces ISC and potentially leads to a severe thermal hazard. Therefore, the thermal stability of the separator has a crucial effect on battery safety.
It is noteworthy that high temperature will affect the viscoelastic behaviors and mechanical strength of polymer, which may further trigger the structural failure of the batteries . 2.1.3. Thermal runaway
Secondly, as shown in Fig. 7 b, when it is exposed to a high temperature above 130 °C, the electrolyte experiences the second radical reaction, turning to solid state from previous liquid state. The full LFP/TSE/Li battery can operate well even at 150 °C.
Thermal Runaway: In the worst-case scenario, excessive heat can lead to thermal runaway, where a battery's temperature increases uncontrollably, resulting in leakage, fire, or even an explosion.
