Ubiquitous Computing
by Anita Campbell on December 12, 2005

"NEC Corporation today announced that it has succeeded in the development of an ultra-thin, flexible, rechargeable battery capable of super-fast (30-second) charging, which can be embedded into smartcards and intelligent paper. The new battery, organic radical battery (ORB), uses a type of plastic called organic radical polymer as its cathode.
Organic radical polymer assumes an electrolyte-permeated gel state, and is the reason why the rechargeable battery is so remarkably flexible and pliant. In addition, the organic radical polymer electrode reaction is extremely fast and the supporting salts migrate through gel state polymer very smoothly.
* * *
Key features of the newly developed battery include:
(1) An exceedingly thin structure (300 microns), which will enable it to be embedded into objects such as smartcards and intelligent paper in the future.
(2) A pliant and bendable structure, as flexible plastic is used as the cathode material.
(3) An ultra-fast charging speed of less than 30 seconds.
(4) A high energy density of approximately 1 mWh (mili Watt hour) per cm squared. This means, for example, that if the ORB was used in an active RFID device, it would support up to approximately several tens of thousands of signal transmissions on a single charge.
(5) Environmentally friendly, it does not contain any harmful metals.
NEC anticipates that its new and unique battery will be used extensively in the future to power all kinds of tiny ubiquitous terminals. The interconnection of networks with battery-powered next generation ubiquitous devices will enable all kinds of objects to become terminals, bringing us closer to a ubiquitous networked society by allowing access to the network anytime, anywhere."
Very interesting. I put this in the category of bleeding-edge experimental. There is nothing to indicate this ultra-thin battery is in production usage anywhere -- or even that it will be anytime soon. But it is inventions such as these that could make the difference in advancing ubiquitous computing from the futuristic vision it is today, to an everyday reality. We are already edging our way, little by little, toward ubiquitous computing, or the "Internet of Things." It will be interesting to look back in 5 - 10 years and see what made the difference.

I\'m looking into RFID batteries for new applications. If anybody could point me into some leads to a good source for wholesale rechargeable RIFD batteries it would be much appreciated.
