MIT Researchers improved well known Lithium-iron-phosphate technology to allow faster flow of ions through material. This made it possible to create batteries that charge and discharge in a matter of seconds when needed.

Research is led by Gerbrand Ceder. MIT news site has a more detailed article about this research.

Now, having this technology available to electric car makers, means you could charge your electric car even faster than the time you currently spend fueling your conventional car. That would be great - that would eliminate one of the biggest pit-stops of electric cars.

According to Gerbrand Ceder, this technology could be available for public in just 2 or 3 years.
