Thermal runaway is a heat-induced chemical chain reaction of battery cells that is triggered by soaring temperatures inside a rechargeable battery as they may result from, for example, the force of an impact in an accident and an ensuing short-circuit.
However, the advancement of LIB technology is hindered by the phenomenon of thermal runaway (TR), which constitutes the primary failure mechanism of LIBs, potentially leading severe fires and explosions. This review provides a comprehensive understanding of the TR mechanisms in LIBs, which vary significantly depending on the battery’s materials.
To mitigate the risks of thermal runaway, manufacturers must take several precautions: Battery Management Systems (BMS): These systems monitor the battery’s state, including its charge level, temperature, and health, to prevent conditions that could lead to thermal runaway.
In the context of containing and mitigating the propagation of thermal runaway in lithium-ion batteries, the choice of thermal barrier materials is crucial. These materials must possess high thermal resistance and stability, be non-flammable, and have the ability to absorb or dissipate heat effectively.
5. Thermal runaway prevention The prevention of TR and the inhibition of heat propagation in the event of TR in LIBs are paramount concerns for ensuring the safety and reliability of these energy storage devices .
Important data need to be recorded, especially heater power (input for the thermal runaway model). The sensibility of exothermic detection should be respected (0.03 °C/min as the limit). The sample should be heated with small steps of temperature change (typically 5 °C).
