FiberCork offers low thermal conductivity, which is essential for minimizing the risk of battery cell overheating. During critical events, such as a thermal runaway, the material acts as an effective barrier to contain the spread of heat and flames within the battery, ensuring the safety of passengers and vehicles.
If the battery heats up, the material absorbs the heat, turns into liquid, and later into gas, and the gas then carries the heat out of the battery pack. Thermal runaway protection in battery packs for EVs depends on multiple factors. Most batteries come with a battery management system that controls the rate of charging to prevent overheating.
Therefore, the efficient and appropriate thermal insulation material design is crucial for LIB packs to effectively reduce or even inhibit the spread of TR. Based on it, in this review, we present the principle and influences of TR to provide the necessity of battery thermal management and thermal insulating materials.
