> Also, because there's gaps in that ultra-lightweight nanotube scaffolding and less extraneous binder and additive materials, a battery containing a given amount of active material can become much, much lighter and more compact. Energy density, both by weight and by volume, stands to jump by factors of 2-3.
This isn't the first company to claim carbon nanotube batteries.[1]

Disclosure: I've worked on the software side of the battery industry, and am skeptical of any battery I'm not holding in my hand.
Um, yes. Still, this seems to be a reasonable way to go, especially since the developer claims to be able to make layers of carbon nanotubes cheaply.
Nawa, though... They announced in 2019 that they would be shipping ultracapacitors by the end of the year. But their products page doesn't list any. They're not a vendor known to Avnet or DigiKey. They announced a super-bike with ultracapacitor boost in 2019, and there are pictures, but none show the bike in motion.
