Just for perspective, the best lithium polymer batteries deliver about 250 Wh/Kg.
The power density for supercaps is pretty good though, as is their longevity.
That graph shows grapheme caps topping out at about 4.5 Wh/Kg energy density.

I’m not getting this. If grapheme caps top out at about 4.5 Wh/Kg energy density....why are they so much more interesting/better/important/powerful than lithium polymer batteries which deliver about 250 Wh/Kg? Isn’t 250 Wh/Kg many orders of magnitude better/important/powerful than 4.5 Wh/Kg?
