Researchers Develop Lightweight Paper Batteries.

The article focuses on a technology developed by Stanford University associate professor Yi Cui and his team which turns a standard office paper into a battery that creates energy source for portable electronics such as laptops and hand held devices. Yi Cui and his team discovered that carbon-nanotube ink infused paper, used as electrodes, offered performance similar to the much-heavier metal electrodes found on lithium-ion batteries. The team is trying to make their technology commercially relevant, like improving their battery's performance.
