Innovations in battery life.
Technology is constantly changing, but sometimes it seems as
though we're stuck with the same old cylindrical AA batteries.
With the proliferation of smaller and more powerful mobile devices,
the need for advances in battery technology has never been greater.
One company making strides is NEC, which has developed an unusual battery that could
become a promising power source for things like smartcards,
intelligent paper or wearable comput-ing devices.
Dubbed the organic radical battery, or ORB, it uses an organic
radical polymer as its cathode. That means it's ultra-thin,
flexible and rechargeable. Its structure is a wafery 300 microns,
and it can be recharged in less than 30 seconds. It is also more
environ-mentally friendly than standard rechargeable batteries
because it can be manufactured without harmful chemicals.
The battery's flexibility makes it a good candidate for thin
and compact devices. RFID cards powered by this type of battery,
for instance, could transmit information over greater distances
than the RFID tags used today.

NEC has not made any decisions on commercialization yet, but it
has created several prototypes. There's no telling when
entrepreneurs might be able to pick up a device that uses an ORB,
but it's an exciting technology to keep an eye on.
