A practical supercapacitor can be made on the bench by almost anyone, as the ever-resourceful [Robert Murray-Smith] demonstrates using mushrooms as his feedstock.

Logitech’s $80 supercapacitor gaming mouse is the most versatile it’s ever made. AA and magnetic charging, Lightspeed and Bluetooth, lightweight and ultralight.

A supercapacitor is a newer concept that combines the design of a battery with the physics of a capacitor. A capacitor has two layers of conductive material with an insulator (like, for example ...

It “poses a question whether [the MIT supercapacitor] is really going to be that practical,” Gevelber said. But the MIT researchers say they have a mixture they call the “sweet spot”: 90 ...

Non-toxic supercapacitors go fully recyclable “The fact that the constituent materials are so readily available opens up a new way to rethink energy storage solutions,” Ulm tells Physics World..

A supercapacitor is an alternative to a battery, capable of storing energy and releasing it very quickly. If this new tech is scalable, it could be huge in the effort to shift toward renewable energy.
