Supercap Q&A Winter 2005

With so much interest in supercapacitors, BEST is doing its part to keep readers up to speed with another technical series from a highly respected expert in the field – none other than John Miller. For this first issue John kicks off with some basic Q&A.

Q How do supercapacitors, ultracapacitors and electrochemical capacitors differ from each other? And how do they differ from pseudo-capacitors or double-layer capacitors?

The three types of capacitors now commonly in use are the electrolytic, the electrostatic and the electrochemical. The 'supers' and 'ultras' are actually both straightforward . . .
