New Rechargeable Battery Charges in 30 Seconds

NEC said 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. This results in little resistance to the charging reaction and an incredibly fast charging time of less than 30 seconds.

The battery is also environmentally friendly unlike to conventional rechargeable batteries, which contain heavy metals such as mercury, lead or cadmium.
