New Nanowire Battery holds 10 times the charge of current Li-ion batteries

Researchers at Stanford have developed a new method of using silicon nanowires in lithium-ion batteries. These new batteries produce 10 times the charge of existing Li-ion batteries. The silicon in typical batteries tends to pulverize during the expand and shrink process of charging and discharging. Nanowires avoid the fracturing problem due to their extremely thin shape which is 1/1000th the thickness of a a sheet of paper. This greatly enhances the batteries performance. The new batteries could be used in anything from laptops to electric cars.
