Another graphene application – supercapacitors
While everybody knows about batteries, supercapacitors seem like a well kept secret. The reason is fairly simple. While capacitors have been used for a long time in electronics, capacitors and their souped-up cousins, supercapacitors, have only recently become candidates for competing with the common rechargeable battery. Supercapacitors store electricity as batteries do, but there are [...]

For real: A new way to produce electricity
It’s not every day that a new way to produce electricity is discovered…although it does seem there is a multitude of approaches. This one involves carbon nanotubes, those jacks-of-all-trades in the nanotech business, nanometer sized tubes of pure carbon. (In this case, think of them as ‘wires’ one-hundred thousandth of the thickness of human hair.) [...]

Go with the flow battery
Did you know that one kind of battery can be refilled with a charge in much the same way as a gas tank? It’s not a new idea. One of the most efficient incarnations of what is called a redox flow battery was developed in the 1980s at the University of New South Wales, Australia. [...]

Rechargeable zinc-air batteries coming to market
If you go to your local home improvement store, the buzz-word in batteries is lithium-ion. As most of us are finding out, these are a lot better than the old alkaline or cadmium rechargeable batteries. But of course, the product cycles of modern technology are doing their thing, and a successor to lithium-ion is already [...]
