Well he started off working on super capacitors I think in college. Or he said he wanted to, I forget. More recently, Tesla has purchased a super capacitor company (Maxwell). I’m using some supercapacitors in a project at work. For $500 we get a super capacitor with the capacity of a $12 battery. For the time being, batteries are way, way ahead on cost.
- darksaints 7y agoI don't know much about costs, but papers like this make me pretty giddy at the prospect of supercapacitor-only cars. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6409971/#sec1-nanomaterials-09-00148title https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6409971/#sec1-n... That energy density is at least as high as current generation lithium ion, which is obviously already feasible for production cars.
- madengr 7y agoSure, but what’s the short circuit current rating from a super capacitor vs a battery. We have used them in thermal battery powered supplies for pulsed electronics. They’ed be useful in cars for acceleration and regenerative breaking, allowing the use of lower current batteries.
