A research group has used nanosheet technology to develop a dielectric capacitor for advanced electronic and electrical power systems. Innovations in energy storage technology are vital for the ...

Every year, the Dutch physics community gets together to celebrate the year in physics. These are some highlights from the meeting. Since it is a meeting, it is not possible to link to published work ...

The concept of using supercapacitors (also known as ultracapacitors, supercaps, etc.), and replacing the batteries in portable micropower applications, 1 is gaining momentum. In fact, it has become ...

In electrical circuits that drive lasers, run cardiac implants, or convert between alternating and direct current, components called capacitors produce large, fast pulses of energy. A new composite ...

Reliable high-capacity energy storage is one of the major challenges we face in developing new electrical technology. From long-range electric cars to backups for variable-output alternative energy ...

Supercapacitor technology has come of age. In less than 10 years, these high-charge electrochemical devices have evolved in two directions from the large, low-voltage cylindrical devices originally ...

Batteries are terrible. Compared to many other methods of storing energy, especially fossil fuels, batteries aren’t very energy dense—that is, a 1-pound battery stores far less energy than is ...

Hybrid "power capacitors" that can store as much energy as lithium batteries, but with much higher charge/discharge rates, a huge range of safe operating temperatures, super-long lifespans and no risk ...

RF ENERGY harvesting techniques for micro-power can be employed for a wide range of radio frequencies, and the license-free industrial, scientific and medical (ISM) radio bands, such as 915MHz and ...

Your phone died. Again. In these scenarios, who among us has not dreamed the dream of a future where our devices charge instantly and last forever. As capacitors—or even more exciting, ultracapacitors ...
