batteries are useless, electric cars are a fantastic idea, but if you power thing with heavy, toxic, and inneficient batteries, all advantages are lost.
saying goodbye to batteries is ever so slightly premature. even at 50Wh/kg it would still only be interesting for some applications and not universally replace batteries which are now as high as 230Wh/kg
you could imagine certain train types using 50Wh/kg batteries that recharges in a couple of minutes at the station or taxis with small range extenders for out range driving. but it's not easy beating batteries weighing 3-5 times less
Why are some people very smart and others are totally stupid.

@system0system0 so we know the difference between the two. How do you know what hot is unless you've experienced cold.

Ions in the electrolyte. That sounds like a battery. I think this must be some battery/capacitor hybrid. A freaking capacitor stores static.

@AtariXcore No, it's a capacitor. Electrolytic capacitors have ELECTROLYTES on the separator.

@seennlisten I don't know of any "finished" technology projects, car manufacturers are still improving on the wheel!

but should it ever reach above 100Wh/kg and still have veyr high power density and unlimited lifespan then it might well be universally appealing.
stuff like flashlights and police radios etc that might not need the absolutely highest density might be able to live with as low as 30Wh/kg
