Thermal runaway in lithium-ion batteries is a critical safety concern, often overlooked until it’s too late. This phenomenon occurs when a battery becomes self-destructive due to uncontrolled thermal conditions, leading to potential hazards.
Generally, lithium-ion batteries become vulnerable to thermal runaway at temperatures above 80°C (176°F). Once this threshold is crossed, the risk of chemical reactions leading to thermal runaway increases significantly. Understanding this temperature limit is crucial for safe battery design and usage.
The thermal runaway of lithium-ion batteries is the phenomenon of chain exothermic reactions within the battery. These reactions cause a sharp rise in the internal battery temperature causing the inner structures of the battery to destabilize and degrade, which eventually leads to the failure of the battery.
The mean peak values extracted from the experiment were 753 °C for the surface temperature, 1080 °C for the internal battery temperature, 3.6 kW of heat, and 4.56 bar of internal pressure during the thermal runaway. In addition to heating the batteries, thermal abuse also occurs due to loose contact with battery connectors.
Lithium-Ion Battery Thermal Runaway Prediction Thermal runaway prediction can be useful in terms of warning users of their abusive behaviors toward the battery or of any hostile surrounding environments around the battery.
Identifying the trigger temperature for thermal runaway is complex, as it varies based on battery composition and design. Generally, lithium-ion batteries become vulnerable to thermal runaway at temperatures above 80°C (176°F). Once this threshold is crossed, the risk of chemical reactions leading to thermal runaway increases significantly.
