Lithium Iron Phosphate Batteries
Lithium Iron phosphate (LFP) is a popular, cost-effective cathode material for lithium-ion cells that is known to deliver excellent safety and long life span, which makes it particularly well-suited for specialty battery applications requiring high load currents and endurance.
Discovered by University of Texas researchers in the mid-90s, LFP cathode offers several key advantages including a high current rating, long cycle life, and superior thermal stability, which makes it one of the safest and most abuse-tolerant cathode material options available to manufacturers. On the other hand, LFP delivers a lower nominal voltage, which results in lower specific energy when compared to other cathode materials on the market. Consequently, LFP batteries tend to have a higher self-discharge than other Li-ion battery types.
