We’ve always been a little sad that supercapacitors aren’t marked with a big red S on a yellow background. Nevertheless, [DiodeGoneWild] picked up some large-value supercapacitors and used his ...

A new material called multiscale reduced graphene oxide could mean faster charging and power delivery than traditional batteries allow.

A team of MIT researchers has figured out a way to create a supercapacitor simply by mixing cement, the binding ingredient of concrete, and a fine charcoal product called carbon black together with ...

Since energy storage devices are often used in a magnetic field environment, scientists have often explored how an external magnetic field affects the charge storage of nonmagnetic aqueous ...
