Thermal runaway is a phenomenon that occurs due to self-sustaining reactions within batteries at elevated temperatures resulting in catastrophic failure. Here, the thermal runaway process is studied for a Li-ion and Na-ion pouch cells of similar energy density (10.5 Wh, 12 Wh, respectively) using accelerating rate calorimetry (ARC). Both cells were constructed
Before the experiments, the LFP/graphite battery was charged to 3.65 V with 20 A by a battery cycler (NEWARE CT-4008Tn-5V10mA-164); the standard charging method is constant current – constant voltage (CC-CV). Afterward, the battery was charged at 3.65 V until the charging current decreased to 0.05C (14 A) at room temperature. DSC tests were
In recent years, ceramic-coated battery separators have also gained popularity in lithium-ion battery technologies because their non-flammable and thermally stable features enhance the mechanical stability and thus ensure the isolation of the electrodes at elevated temperatures. 3 Ceramic-coated separators are considered one of the most effective and
If the battery is exposed to abused operating conditions, such as thermal abuse [[6], [7], [8]], mechanical abuse [[9], [10], [11]], and electrical abuse [[12], [13], [14]], the TR can be induced easily because of abnormal temperature rise.Then series successional exothermic side-reactions would occur inside the LIBs, including breakdown of the solid-electrolyte interphase

Lithium-ion batteries used in EVs, perform optimally within a specific temperature range—ideally between 26-35°C (68 to 86°F).More than 35°C (86°F) can lead to higher rate of degradation of the battery components,

For example, the heat generation inside the LIBs is correlated with the internal resistance. The increase of the internal temperature can lead to the drop of the battery resistance, and in turn affect the heat generation. The change of resistance will also affect the battery power.
The high temperature effects will also lead to the performance degradation of the batteries, including the loss of capacity and power , , , .

Heat generation within the batteries is another considerable factor at high temperatures. With the stimulation of elevated temperature, the exothermic reactions are triggered and generate more heat, leading to the further increase of temperature. Such uncontrolled heat generation will result in thermal runaway.
Furthermore, if the single cell is trapped in thermal runaway, it is particularly crucial to prevent cascading propagation within battery modules. 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.
Common thermal issues related to lithium ion batteries include capacity or power fade, self-discharge, thermal runaway, electrical inconsistency of the battery pack and poor cold temperature performance [ 20 ].The battery performance was also significantly affected by temperature variation within the battery module [ 21, 22 ].
