This thin-film carbon ultracapacitor electrode, shown at the image, is about 50 micrometers on each side. The zigzagging, porous regions are the active part of the device. ...

Big Energy Storage in Thin Films

Energy storage devices called superapacitors can be recharged many more times than batteries, but the total amount of energy they can store is limited. This means that the devices are useful for providing intense bursts of power to supplement batteries but less so for applications that require steady power over a long period, such as running a laptop or an engine.

Now researchers at Drexel University in Philadelphia have demonstrated that it's possible to use techniques borrowed from the chip-making industry to make thin-film carbon ultracapacitors that store three times as much energy by volume as conventional ultracapacitor materials. While that is not as much as batteries, the thin-film ultracapacitors could operate without ever being replaced. Audio »
