Soft, flexible, wearable power is the stuff many scientist are working on, not only for the wearable electronic community as many other applications like to use bendable, sustainable, power providing sources for our devices on the go.
A group of scientist at the Uppsala University in Sweden led by scientist Albert Mihranyan try to develop light, ecofriendly, inexpensive batteries consisting entirely of nonmetal parts.
At the center of their research is a novel nanostructured high-surface area electrode material for energy storage applications composed of cellulose fibers of algal origin individually coated with a thin layer of polypyrrole, a conductive polymer.
This unique design of the battery cell was according to the researchers ‘surprisingly simple yet very elegant since both of the electrodes consist of identical pieces of the composite paper separated by an ordinary filter paper soaked with sodium chloride serving as the electrolyte.’
Oh well, that is a bit beyond my understanding to judge but another interesting fact is: the battery recharged faster than conventional rechargeable batteries.
To sum up the good news of this research: this new technology enables batteries to be paper thin, can be made on large areas, recharges faster than most of the current battery technologies and are ‘relatively simple’ to make.
All this is the stuff wearable electronic is waiting for, large areas on clothing with a power storing layer on the inside and a power generating (solar) layer on the outside.
