There have been constant news articles coming out over the past few years claiming the next big thing in supercapacitor and battery technologies. Very few actually turn out to work practically.
The most exciting things to happen in the last few years (from an average citizen's perspective) are the wider availability of sodium ion batteries (I believe some power tools ship with them now?), the continued testing of liquid flow batteries (endless trials starting with the claim that they might be more economic) and the reduction in costs of lithium-ion solid state batteries (probably due to the economics of electric car demand).
FWIW the distinction between capacitors and batteries gets blurred in the supercapacitor realm. Many of the items sold or researched are blends of chemical ("battery") and electrostatic ("capacitor") energy storage. The headline of this particular pushes the misconception that these concepts can't mix.
My university login no longer works so I can't get a copy of the paper itself :( But from the abstract it looks first stage, far from getting excited about:
"holds promise" and "has the potential" are not miscible with "May Be the Beginning of the End for Batteries".

Scihub my brother ๐
Just email one of the researchers and ask them to send you a copy
We have the internet man, just bug another human and wait a few days to hear back from them.
Like I know that's what you are "supposed" to do. But public money public knowledge, I refuse to accept that this is somehow an acceptable state of things.
