Japanese company NEC has developed a lightweight, flexible battery that is less than a millimetre thick and can be recharged in half a minute.
It is called the Organic Radical Battery (ORB) and is based on a type of plastic that exists in a gel state. The gel allows the battery to be extremely pliant, with a thickness of 300 microns.
ORBs could eventually be embedded into devices such as smart cards, wearable computers and intelligent paper. Currently the battery, when in card form, can be recharged with a card reader device in 30 seconds.
The absence of harmful chemicals typically used in rechargeable batteries also makes it quite environmentally friendly, according to NEC.
