> gravimetric energy density of up to 1.76 MJ kg−1

Gasoline has 47 MJ/kg [0], in 2007 Lithium-ion batteries were 0.36 - 0.90 MJ/kg [1]

I am content with a research which already nearly doubles the energy density of Li-ion batteries (0.9 to 1.76). I also think the idea of using carbon instead of lithium is a step forward.

Now, how to squeeze it into an iPhone 14!
