LiFePO4 Features : 1.The Lithium Iron Phosphate Battery is a type of rechargeable battery based on the original lithium ion chemistry, created by the use of Iron (Fe) as a cathode material. It is not yet widely in use.LiFePO4 cells have a higher discharge current, do not explode under extreme conditions and weight less but have lower voltage and energy density than normal Li-ion cells.
2.Iron (Fe) is an intrinsically sager cathode material than Cobalt (Co) .The Fe-P-O bond is stronger than the Co-O bond so that when abused (short circuited, overheated, etc) the oxygen atoms are much harder to remove. This stabilization of the redox energies also helps fast ion migration. Only under extreme heating, generally over 80°C, does breakdown occur which prevents the thermal runaway that LiCoO2 is prone too .
Advantages Disadvantage 1.Extremely High Rate Capability 2.Safe Lithium Battery 3.Good storage characteristics 4.Good high temperature performance 1.Lower capacity than standard Li-ion 2.3.2 V nominal voltage VS 3.6V Typical Applications Electric bicycle battery ,Power tools, Electric vehicle applications, Club car, Emergency lighting high temperature condition use .
