'Nanoball' batteries could recharge car in minutes http://apocadocs.com/s.pl?1236873783
Byoungwoo Kang and Gerbrand Ceder at the Massachusetts Institute of Technology have revealed an experimental battery that charges about 100 times as fast as normal lithium ion batteries. Their battery contains a cathode made up of tiny balls of lithium iron phosphate, each just 50 nanometres across. The balls quickly release lithium ions as the battery charges, which travel across an electrolyte towards the anode. As the battery discharges, the lithium ions move back across the cell to be re-absorbed by the nanoballs.... Bigger batteries for plug-in hybrid electric cars could charge in just 5 minutes -- compared with about 8 hours for existing batteries -- though this would require a very high-powered charger.
