Huge new battery breakthrough.

Extreme Tech link

"New lithium-ion btatery design that is 2,000 times more powerful, recharges 1,000 times faster."

The chemistry isn't much different (so energy density isn't leapfrogging), but the anode and cathode are on 3-D styrofoam cells instead of 2-D surfaces, so it's like having millions of very tiny batteries with extremely high charge and discharge rates wired in parallel.

Its performance is like a supercapacitor but with the energy density of the best current batteries.
