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.
Lifepo4 Battery performance :
Good safety performance, high quality material, national standard tests passed.
Good discharge performance at low temperature, 70% SOC -20
Long cycle life; 1C/1C 100%DOD,at 3000times, with 80%SOC
