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 ...

Lots of single-use water bottles made from poly(ethylene terephthalate) (PET) end up in landfills, but there’s a growing interest in upcycling them instead ...

Researchers have built a high-capacity energy-storage device using a metal–organic framework (MOF) — a porous material with many desirable properties. MOFs are networks of metal ions linked together ...

Scientists have set themselves the goal of improving these ubiquitous, fast storage devices by developing a new kind of electrode based on graphene. Supercapacitors are the nimble little siblings of ...
