Lithium Iron Phophate Batteries
Lithium Iron Phophate(LiFePO4) batteries may soon take over the market for electric carsand plug-in electric vehicles. Based upon lithium ion technology,LiFePO4 batteries offer greater safety plus higher output thanlithium cobalt dioxide (LiCoO2) batteries that are used commonly inlaptops, mp3 players and cell phones.
Developed by Dr. John Goodenough (as opposed toBoris Badenov) at the University of Texas, LiFePO4 batteries haveseen wide acceptance recently in Asian countries, but still havenot made inroads in the U. S. marketplace. This is about to change,however.
With recently safety concerns over other laptopbatteries catching fire and the ensuing recall, LiFePO4 batteriesare now being used by some manufacturers as a safer alternative.LiFePO4 batteries are also being used in electric bicycles and powerscooters.
For electric vehicles and plug-in electric cars, theLiFePO4 batteries such as those on the www. osnpower.com websiteoperate well in temperatures up to 400-degrees F, last for 6 to 7years at a charge-discharge cycle of over 2,000.
The biggest player in the LiFePO4 marketplace forelectric vehicles is A123 Systems that has teamed up withGM to develop these Lithium IronPhophate batteries for the Chevy Volt plug-in hybrid. Another bigplayer is Lithium Technology Corporation whohas been working with GM, Toyota and U. C. Davis to develop LiFePO4batteries for all-electric and hybrid vehicles.
We are on the cusp of a revolution in batterytechnology. Tomorrow’s choice for safe, high-output rechargeablebatteries for vehicles will be Lithium Iron Phophate.
