By replacing the graphite electrode with silicon nanowires, Amprius achieves higher power density and faster charging for its ...

Batteries are made up of two parts. One part, the anode, “holds on” to its electrons very loosely. The other part is the cathode, and it has a strong pull on the electrons and holds them tightly.

Lithium-sulfur batteries have never lived up to their potential as the next generation of renewable batteries for electric ...

It’s this oxide layer that actually acts as the dielectric in electrolytic capacitors, not the paper separator between the anode and cathode strips. Winding the foils together with the paper ...

Sam Battle] is no stranger to these pages, nor is his Museum is not Obsolete. The museum was recently gifted an enormous Nixie tube created by Dalibor Farný, a B-grade (well, faulty) unit that ...

Solid tantalum capacitors are typically comprised of a pellet-shaped anode, formed from tantalum powder, and a cathode constructed of manganese dioxide. The image below shows a cutaway view of a solid ...
