When thermal runaway initiates, it can produce excessive heat, leading not only to the battery’s destruction but also risking adjacent cells in a multi-cell configuration.

Understanding the science behind thermal runaway can aid in developing preventive measures. Often, lithium-ion batteries will degrade, resulting in a gradual increase in internal resistance. This change can elevate the heat generated during normal operation, eventually leading to overheating. Once the temperature exceeds around 125°C (257°F), it can initiate a series of exothermic chemical reactions within the cell substrate. As the process continues, the heat and pressure created may lead to venting and, ultimately, combustion. Immediate action becomes vital, but prevention through the incorporation of robust thermal management systems significantly reduces the risk of thermal runaway.
