I like how they don't specify what _kind_ of chemical battery they're 
comparing to. Typical estimates for nanotube ultracapacitors is a peak 
of about 60 Wh/kg, which is better than your average lead-acid battery 
but less than 50% of a good lithium-ion battery and less than 25% of a 
good thin-film lithium battery.
