Bendable, Paper-based Battery

There are so many uses for this technology!!!! It could cause battery prices to decrease, spur innovative portable devices, and reduces, further, the size of many electronic devices. Just think of how small your MP3 player can be if the battery wasn't as big as it is now.
The researchers at Rensselaer Polytechnic Institute won't be crowned the first to develop a flexible (or paper-based, for that matter) battery, but their minuscule prototype "is an integrated device, not a combination of pieces" as others typically are. The battery uses "paper infused with an electrolyte and carbon nanotubes that are embedded in the paper," and could eventually be utilized in combination with solar cells or "scaled up and shaped into something like a car door, offering moving electrical storage and power when needed." Currently, however, the wee samples can release just "2.3-volts, or enough to illuminate a small light,"
