Thermal events in lead-acid batteries during their operation play an important role; they affect not only the reaction rate of ongoing electrochemical reactions, but also the rate of discharge and self-discharge, length of service life and, in critical cases, can even cause a fatal failure of the battery, known as “thermal runaway.”
Even in extreme operating conditions such as a thermal runaway, direct liquid cooling has the capability to enable safe battery operation due to the high fire point and phase transition characteristics of coolants.
