Lithium Iron Phosphate (LiFePO4)
Li-phosphate offers good electrochemical performance with low resistance. The key benefits are high current rating and long cycle life, besides good thermal stability, enhanced safety and tolerance if abused. Li-phosphate is more tolerant to full charge conditions and is less stressed than other lithium-
ion systems if kept at high voltage for a prolonged time.
