Excellent technology, but why do they switch units so those of us who are tired and don't want to have to figure it out, can't?

A typical lithium-ion battery can store a charge of 1 microfarad per square centimeter. The energy membrane ups that to 0.2 farads.


If the writer is a science writer then how tough would it be for them to tell us both in microfarads?

we really need much more powerful batteries.

like an electric car that could go a 1000 miles, or something to power a fembot for a week...

Cause it'd be 200,000 microfarad and it's easier to say and understand .2 farad....at least to me it is

When I was studying Electrical Engineering, a Farad was a measure of capacitance, and the values were usually micro- or pico-farads. Nobody would dream of measuring battery capacity in farads. It was usually watt-hours per pound. But if we can get a battery to go 200 miles on a charge, which would take only five minutes; it could give gasoline some serious competition.

Wonder if they are/will be publicly traded....

If all is well and good with the claims - I sure hope so. Get in early!

There are some serious engineering challenges associated with turning this research into a practical battery. Supercapacitors have been around for years, and no one has been able to get around the practical limitations dielectric absorption, sparking, and low energy storage density by weight. The fact that even theoretical values for J/g or W/g were not reported makes me very suspicious.

Well find out and let us know
