'Nanoball' batteries could recharge car in minutes - tech - 12 March 2009 - New Scientist
Researchers at MIT have developed a lithium battery that charges 100 times faster than current lithium battery designs. The trick is a cathose made up of tiny balls of lithium iron phosphate, 50 nm in diameter, that speed the lithium ion discharge process. They predict that a cell phone with this type of battery would charge in about 10 seconds, and a hybrid car in about 5 minutes.
