A team of scientists has invented a ground-breaking way of storing electricity – in PAPER.
The experts from Sweden have developed a remarkable thin material which has the capacity to store power. The so called ‘power-paper’ is 15 centimetres in diameter and less than 0.5 millimetre thick. Yet it can hold one farad electrical capacitance – roughly the same as supercapacitors used in many devices at the moment. The ultra-thin material is made from nanocellulose and a conductive polymer and only takes seconds to recharge.
“What we have done is to produce the material in three dimensions. We can produce thick sheets.”
The amazing ‘battery’ looks like a small strip of black paper and can be folded up – while still working. However it feels like plastic to touch. Researchers claim ‘power paper’ could have a significant impact on how we store charge in small devices, such as mobile phones. They say the paper is light, requires no dangerous chemicals or heavy metals, and is waterproof.
