NEC Develops New Flexible, 30 Sec Rechargeable Battery

Filed under: — By Aviran Mordo @ 10:12 am

NEC ORBNEC Corporation announced that it has succeeded in the development of an ultra-thin (300 microns), 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. This results in little resistance to the charging reaction and an incredibly fast charging time of less than 30 seconds. Not only is this new battery thin, flexible and rechargeable, but it is also environmentally friendly as unlike conventional rechargeable batteries, it does not contain any harmful heavy metals such as mercury, lead or cadmium.

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.

NEC will continue to carry out aggressive R&D in this area toward enhanced performance and reliability of thin, flexible rechargeable ORBs.
