Can LiFePO4 Batteries Catch Fire?

Yes, LiFePO4 lithium batteries can catch fire, but they are generally safer than other types of lithium batteries. LiFePO4 chemistry have superior chemical and thermal stability because of inherently olivine structure, which makes them harder to ignite and better able to handle higher temperatures. However, under certain circumstances, such as a direct puncture or exposure to an external heat source, lithium iron phosphate batteries can still catch fire. If a lithium LiFePO4 battery does catch fire, it will vent gas that can ignite like propane and potentially burn down the entire battery pack. Therefore, while LiFePO4 battery packs are safer, it’s important to handle them with care and use appropriate safety measures.
