Moving Electric double-layer capacitor to Supercapacitor edit
Electric double-layer capacitors (EDLCs), invented 1957, have seen a dramatic change in understanding of their capacitive charge storage from a pure physical function between Helmholtz double-layers to an additional pseudocapacitive chemical charge storage with redox reactions, electrosorption and intercalation processes. Because nowadays (2013) an electrochemical capacitor is not only an EDLC anymore the question comes up how to name this very special capacitors.
Generally in science publications all the different developments of the last years are united under the term “electrochemical capacitors”. But if a development gets a discrete component, the names are manifold. Supercap, Ultracap, Goldcap, Greencap, a lot of manufacturer related names exist.
A look through the science literature shows, that roughly 70 to 80 % of the authors uses the term “Supercapacitor” (see: A Bibliometric Analysis of the International Literature in Supercapacitors, Francesco Lufrano* and Pietro Staiti, Int. J. Electrochem. Sci., 4 (2009) 173 – 186 PDF)
A google research gives 730,000 results for Supercapacitor, for Ultracapacitor only 363,000 (Date: 2013-05-07)
As of 2013 the term supercapacitor has prevailed as the alternative term instead of EDLC or ultracapacitor. One of the reason is surely the respect for B. E. Conway who coined the term supercapacitor. The term “ultracapacitor” also often to be found is used like a trade name for the capacitors from Maxwell, the market leader, and that is a little bit close to advertising.
So I am asking the admins to move the text from EDLC to Supercapacitor and create a redirect. --Elcap (talk) 08:19, 7 May 2013 (UTC)
