Lithium Iron Phosphate (Li-Fe) is new generation Li-Ion rechargeable battery for high power applications, such as Electric Vehicles, Power Tool , RC hobby.  Li-Fe/Li-Fe-PSO4 cells features with high discharging current,  much safe and non explosive, Soon, we¡¯ll probably be seeing Lithium Iron Phosphate (Li-Fe) batteries being used in most electric cars and bikes. This new battery type is set to dominate the market. Based upon lithium ion technology, LiFePO4 batteries offer many advantages over lithium cobalt dioxide (LiCoO2) batteries which are commonly used in laptops, mp3 players and cell phones.

In electric vehicles, Li-Fe batteries offer greater range, power and safety. Li-Fe chemistry is also environmentally friendly ¡ª it¡¯s the least toxic of all the battery types.

For electric vehicles and plug-in electric cars, the Li-Fe batteries will typically perform well in temperatures up to 400-degrees F, last for 6 to 7 years at a charge-discharge cycle of over 3,000.

Here¡¯s a list of all the advantages of Li-Fe batteries:
Safe technology ¡ª will not catch fire or explode with overcharge
Over 2000 discharge cycles life compared to typically around 300 for lead acid
Double the usable capacity of similar amp hour lead acid batteries
Virtually flat discharge curve means maximum power available until fully discharged (no ¡°voltage sag¡± as with lead acid batteries)
High discharge rate capability, 10C continuous, 20C pulse discharge
Unlike lead acid batteries, can be left in a partially discharged state for extended periods without causing permanent damage
Extremely low self discharge rate (unlike lead acid which will go flat quite quickly if left sitting for long periods)
Does not suffer from ¡°thermal runaway¡±
Can be used safely in high ambient temperatures of up to 60C without any degradation in performance
Maintenance free for the life of the battery
Can be operated in any orientation
Does not contain any toxic heavy metals such as lead, cadmium, nor any corrosive acids or alkalies thus making Li-Fe batteries the most environmentally friendly battery chemistry available
Li-Fe cells are of solid construction ¡ª there are no fragile/brittle plates made of lead which can be prone to failure over time as a result of vibration
Can be safely rapidly recharged ¡ª when fully discharged can be brought to a state of over 90% fully charged in 15 minutes
