According to Gizmag and the American Chemical Society publication, NANOLetters, the researchers have come up with a promising new battery technology.
Scientists,Gustav Nystrom, Aamir Razaq, Maria Strømme†, Leif Nyholm and Albert Mihranyan at Uppsala Universitet in Sweden were looking for a way to turn deadly “blooming” algae found in oceans and seas into batteries.
The departments of Nanotechnology and Functional Materials, Engineering Sciences, and Materials Chemistry at The Ångstrom Laboratory at Uppsala University created a new type of lightweight battery. This battery is composed of taking cellulose fibers from algae and coating them with a 50nm “thin layer of polypyrrole”.
Batteries made this way, have charging capacities of “between 25 and 33 mAh g−1 or 38−50 mAh g−1 per weight of the active material”. These batteries could be charged with currents as high as 600 mA cm−2. They would only lose six percent of their charging capacity after 100 charges. In layman’s terms, these batteries are extremely light and can be charged in “11.3 seconds at 320 mA”.
The algae batteries tested were not optimally packaged and the laboratory is working on that issue now. So far they have created a battery that was capable of taking 1000 charges.
There is much still to be done before these batteries hit the market. But they show promise since they should be easy and inexpensive to mass produce.

I am very happy to see that the problems currently plaguing today's laptops and cell phones can now be solved. Paper thin algae batteries will help break new ground in the way batteries are looked at overall. Charging times will become minimal, and a charge will be retained for a much longer time. Mother Nature always has the answer.
