What's wrong with C0G?
magicalhippo•8mo ago
Very low dielectric constant, so low capacitance for a given size[1].

It also seema these devices are more 2D than 3D so surface area matters more than volume[2].

> Very low dielectric constant, so low capacitance for a given size

If they can make it precise, maybe they could be use in RF. But i think temperature performance might be a problem.

marcosdumay•8mo ago
They are not even the same kind of component.

If you try to make an integrator out of this thing, you'll have a very bad time.

myself248•8mo ago
Sounds like a good match for sensor nodes where energy harvesting may be slow and consumption is intermittent. You don't need massive energy capacity, but you need good power density to support transmit bursts, and you need very high cycle durability.
scld•8mo ago
Yeah, as long as self-discharge/leakage rates are acceptable, there are a lot of use cases for this middle ground tech.

Why Zinc if Carbon is sufficient?

From "Eco-friendly artificial muscle fibers can produce and store energy" https://news.ycombinator.com/item?id=42942421 :

> "Giant nanomechanical energy storage capacity in twisted single-walled carbon nanotube ropes" (2024) https://www.nature.com/articles/s41565-024-01645-x :

>> 583 Wh/kg

That's with mechanical twisting though; graphene supercapacitors in general have lower energy density than (micro-) capacitors?
