Do we have any theories on the density? Do they "just" fill up faster? Or can they be denser? We have lots of cool tech now that is limited imo by the fact that Gasoline is just so damn dense and our best batteries don't come close.
Gasoline is at 47.5 MJ/kg ^fn1 and LiOn is at 0.36-0.954 Mj/kg^fn2
Looks like as of 2016 a theorized coil superconducting battery has about 2 Mj/m^3^ while Gasoline is 30 Gj/m^3^^fn1
:(
Eager to see what other novel ways we can use this material though. If it is cheap and easy to make surely new ideas will be flowing fast.
