Paper Battery - Low cost, light weight and high performance. Think about the endless possibilities if this becomes commercial. Scientists at Standford University in California have successfully turned paper coated with ink made of silver and carbon nanomaterials into a 'paper battery'. The same feature that helps ink adhere to paper allows it to hold onto the single-walled carbon nanotubes and silver nanowire films. Silicon nanowires have been found to be made into batteries 10 times as powerful as lithium-ion batteries. Amazing. Things will start shrinking again.
