NEC Corporation has developed an ultra-thin, flexible, rechargeable battery capable of super-fast (30-second) charging, which can be embedded into smartcards and intelligent paper.
The new organic radical battery (ORB) is not only thin 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.
The high energy density of the new battery is approximately 1 mWh (miliWatt hour) per cm squared. This means, for example, that if the ORB was used in an active RFID device, it would support several tens of thousands of signal transmissions on a single charge.
NEC anticipates that its new battery will be used extensively in the future to power all kinds of tiny ubiquitous devices.
