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.”
Similar with other types of batteries, high temperature will degrade cycle lifespan and discharge efficiency of lead-acid batteries, and may even cause fire or explosion issues under extreme circumstances.
Temperature plays a key role in battery operation as it affects the cycle life, performance, and available capacity. The PbA battery system is designed to perform optimally at ambient temperature (25°C) for performance, capacity, and cyclability.
There are two factors that affects battery capacity, ambient temperature and discharge rate. Ambient temperature can affect battery parameters such as voltage,
Thus, under certain circumstances, it is possible to lower the temperature of the lead-acid battery during its discharging.
The aim of this study is to look at a less appreciated fact that during lead-acid battery discharge, an entropy-based phenomenon leads to a cooling effect, which may not be intuitively apparent as it is often negated by Joule heating due to large current flow.
