“... improving the cathode material could eventually increase the voltage and energy density.”

Low energy density is the basic problem with batteries.
Fuel is always orders of magnitude better.
Sounds like this kind is even worse than what we use now.

But cheap.

I read where use of graphite in the form of carbon nanotubes as a battery cathode increases the surface area by a huge amount.
