The Koreans keep pumping out devices that boast DMB radios, multi-megapixel cameras, and unique swiveling designs, but what about powering these multifunction devices? Korea-based Rocket has announced a paper battery that "does not include toxic chemicals nor cause explosion or fire." Taking a little direct poke at Sony, are we?

The ultra-thin and flexible power pack can be used in a number of applications, most notably in an "RFID tag, smart card, cosmetics and drug delivery system, among others."They say that the battery is well suited for "whitening, anti-aging, wrinkle care and moisturizing" devices.
