Lithium iron phosphate (LiFePO4) batteries, while generally safer than other lithium-ion battery chemistries, can still catch fire under certain conditions. Several factors contribute to these incidents. Internal short circuits are a primary cause. These can originate from manufacturing defects, such as poor cell construction or damaged separators within the battery. External damage, such as punctures or crushing, can also lead to internal shorts. Overcharging, where the battery is charged beyond its safe voltage limit, generates excessive heat and is a significant risk factor. This can be caused by faulty chargers or a malfunctioning battery management system (BMS). Over-discharging, pushing the battery to a dangerously low voltage, can also create heat and instability. Environmental factors, like extreme temperatures, both high and low, can degrade the battery's performance and increase the risk of fire. Finally, poor thermal management, either a lack of effective cooling or inadequate heat dissipation, can lead to thermal runaway, a chain reaction that rapidly increases temperature and results in fire. Proper handling, storage, and maintenance are critical to mitigating these risks. Using certified chargers and avoiding exposure to extreme temperatures are essential safety precautions.
Common causes of LiFePO4 battery fires include internal short circuits, overcharging, over-discharging, external damage, and extreme temperatures.
