The invention is a battery comprised of an electrical current collector constructed of carbon or lightweight graphite foam. This foam exhibits a sizeable increase in surface area for chemical reactions to take place and eliminates the need for heavy lead plates found in traditional batteries. The graphite material resists corrosion and sulfation build-up, thus contributing to longer battery life and is lighter in weight than today’s lead acid batteries.

That’s one of those things that you look at and say “Of course”. Increase the surface area, to create a more efficient battery.
I’m a big fan of tweaks like this.
The pure simple step that makes things that much better.
