It’s too bad there isn’t some kind of liquid battery which you could just quickly top off at refueling stations with virtually zero downtime. Yes, like gasolin

Yes, like gasoline. But still batteries. Maybe some kind of bearing sized batteries which can be poured like a fluid?
- dafelst 1y agoYou are describing a fuel cell battery https://en.wikipedia.org/wiki/Fuel_cell https://en.wikipedia.org/wiki/Fuel_cell Well established and even commercialized (Toyota sells fuel cell cars today IIRC), just not as cost effective in cars from a full infrastructure perspective (fueling specifically).
- coderenegade 1y agoI think they might mean something closer to a flow battery, where, in principle, you should just be able to replace the electrolytes in a discharged state with new electrolytes in a charged state. Current flow batteries have very low energy density, though. I've always been partial to fuel cells, and in some ways they're ahead of the curve relative to standard batteries. For instance, solid electrolytes have been a thing for a while in fuel cells, and in both flavors of exchange. The challenge has always been overcoming sluggish kinetics with either better catalysts, or heat. It makes me wonder if there's a useful solid state battery that runs hotter than typical batteries, that would be useful for hybrid automotive applications.
- AaronAPU 1y agoI wasn’t describing that, I was describing individual batteries which are small enough to be effectively liquid in aggregate.
