This video explains how capacitors work and why they are essential in modern electronics. Capacitors store and release electrical energy, helping to stabilize voltage and filter signals across a wide ...

It is possible to combine the high-energy density of batteries with the high-power output of super capacitors in a single system, thanks to liquid energy storage materials, report scientists.

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 ...

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 ...

Capacitors are tiny components found in almost every electronic device, but most people have no idea what they do. This video ...

Berkeley Lab scientists create microcapacitors with ultrahigh energy and power density. The microcapacitors are made with engineered thin films of hafnium oxide and zirconium oxide. The technology ...

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 ...

A magnetic resonance imaging method for peering inside capacitors while they are charging and discharging is allowing researchers to scrutinize the ion dynamics that govern the operation and ...

"Supercapacitors" take the energy-storing abilities of capacitors (which store electrical charge that can be quickly dumped to power devices) a step further, storing a far greater charge in a much ...
