A lithium iron phosphate (LiFePO4 or LFP) battery is a type of rechargeable lithium-ion battery that uses lithium iron phosphate as the cathode material. Known for its safety, thermal stability, and long cycle life, LFP batteries are less prone to overheating and thermal runaway compared to other lithium-ion chemistries. They offer consistent performance, a long lifespan, and are commonly used in electric vehicles, solar energy storage systems, and portable electronics. While they have a lower energy density than some other lithium-ion batteries, their enhanced safety and durability make them a preferred choice for applications where reliability is critical.
