A Revolution in Lithium-ion Battery Technology

A123’s battery is made from nanoparticles of lithium iron phosphate modified with trace metals

A123’s batteries will make lithium-ion technology practical for the auto industry. Instead of cobalt oxide, they use an electrode material made from nanoparticles of lithium iron phosphate modified with trace metals. The resulting batteries are unlikely to catch fire, even if crushed in an accident. They are also much hardier than conventional lithium-ion batteries: A123 predicts that they will last longer than the typical lifetime of a car.
