From the referenced article: "Compared to batteries, supercapacitors also have faster charge-discharge rates, lower internal resistance, higher power density, better cycling stability, and the ability to use external fluids as electrolytes." Have we ever had a supercapacitor that had higher energy density than a lithium ion battery? Is this some amazing new breakthrough in energy density? If so, man, they really really buried the lead.

They always were ;-) But now that they've burnt their leadership role in engineering, they realize it's one of the few profit centers left.

Shouldn't he be arrested for believing AOL still exists?
