Turbo-Charging Batteries

I´m sure that everybody knows that charging batteries take some time - that means some hours. But now MIT professor Gerbrand Ceder and fellow researcher Byoungwoo Kang have developed a battery material they say can both discharge and recharge its energy up to 100 times faster than of today´s batteries. So we could be able to charge a cellphone battery within a few seconds. That also could help to develop cars powered with batteries. They developed a new lithium iron phosphate particles in a glassy film (lithium pyrophosphate) just a few nanometers thick. New batteries should be available within 2 or 3 years.
