Lithium-ion batteries, which store three to four times more energy per unit mass than traditional batteries, are now used extensively in portable electronic devices (computers, cell phones, MP3 players, etc.). The positive electrode materials in these batteries are highly effective but too expensive to be used in the large batteries needed for electric vehicles and second generation hybrid vehicles. In the future, these applications may rely on lithium iron phosphate: it is environmentally friendly and has exceptional properties combined with low cost and good thermal stability (important for safety reasons). All these qualities make it the best candidate to be used in lithium batteries for future electric cars.
