Lithium Iron Phosphate (LiFePO4) Battery gradually gains market acceptance as the replacement for lead acid and nickel cadmium battery because of its low cost, non-toxicity, high abundance of iron, its excellent thermal stability, safety characteristics, good electrochemical performance and high specific capacity.
LiFePO4 cells design has positive electrode of LiFePO4 and negative electrode of carbon with nominal voltage of 3.2V. The cells are not toxic and do not incinerate or explode under extreme conditions. In addition, they have higher discharge current and much higher cycle life.
