Nah, 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," but the idea of using these things to power pacemakers and the like isn't that far fetched.

Nearly a year after NEC rolled out its paper-thin ORB batteries, Korean battery manufacturer Rocket is launching (ahem) its own uber-thin battery. While juicy, scientific details aren't readily available, we do know that the "paper battery" won't include any toxic chemicals, is "flexible and thin," and molds together the companies "thin film technologies" with its battery knowledge. The company hopes to entice heavy RFID users, smart card manufacturers, and "cosmetic / drug delivery system" providers to utilize the paper battery in powering the already-miniscule devices. Oddly, Rocket also envisions its new creation being used in "teeth whitening, anti-aging, and wrinkle care," though we're not exactly sure how electrifying a tooth will brighten your smile. Nevertheless, the company hopes to have its newfangled power source attached to crates and body parts real soon, and confidently assures us that it "doesn't cause explosions or fires." Phew.
