Nanoballs speed up battery recharge

Byoungwoo Kang and Gerbrand Ceder at the Massachusetts Institute of Technology have revealed an experimental battery that charges about 100 times faster than normal lithium ion batteries.
To increase the rate, the battery's surface area was increased by making the cathode out of tiny balls of lithium iron phosphate, each just 50 nanometers across.

Electric vehicles recharge in minutes

The researchers calculate that if cellphone batteries can be made using this material, they could charge in 10 seconds. Bigger batteries for plug-in hybrid electric cars could charge in just 5 minutes - compared with about 8 hours for existing batteries.

When? "2 or 3 years"

How long until we can buy these batteries?

Because there are relatively few changes to the standard manufacturing process, Professor Ceder believes the new battery material could make it to market within two to three years. BBC News
