Nanocapacitors with Big-Energy Storage
Nanopore arrays combine high power and storage capacity.

By Katherine Bourzac

The ultimate electronic energy-storage device would store plenty of energy but also charge up rapidly and provide powerful bursts when needed. Sadly, today’s devices can only do one or the other: capacitors provide high power, while batteries offer high storage.

In a paper published online this week in the journal Nature Nanotechnology, the Maryland group describes making 125-micrometer-wide arrays, each containing one million nanocapacitors. The surface area of each array is 250 times greater than that of a conventional capacitor of comparable size. The arrays’ storage capacity is about 100 microfarads per square centimeter.

Holy crap…!! That’s impressive as hell for something so relatively-easy to manufacture.

Imagine an electric car that can go a thousand miles on a charge and recharge in under 30 minutes.

This is the research that will make this possible.
