Just to share, seem to be an intersting project:

http://www.wired.com/autopia/2011/04/prieto-battery/Researchers at Colorado State University have developed a battery with a three-dimensional interior architecture that uses copper nanowires to store twice as many lithium ions as conventional lithium-ion batteries. Team leader Amy Prieto, pictured with her students, says the prototype, about the size of a cellphone battery, could recharge in about 12 minutes.

Amy Prieto of Colorado State University is developing a new battery technology that utilizes copper antimonide nanowires, and an ultra thin polymer electrolyte. Once fully developed, the battery is expected to offer a huge increase in power density, a reduction in the time it takes to charge, and almost unlimited recharge cycles.
