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.
