Three times the energy density is more than amazing, it's incredible. There are limits with the difference in energy states for the battery chemistry that makes this... unlikely.

To do 3x by volume or weight, you need to switch to a fundamentally different energy storage approach e.g. ultracapacitors or an oxidizing battery.
