Cancellara's battery

Electrolytic capacitors do. That is the most common type of large capacitor. They are polarized. See https://en.wikipedia.org/wiki/Electrolytic_capacitor Of course. I've asked the question (battery or capacitor) on the sci.chem.electrochem.battery group. If any of the old guard still read it, we should get a definitive answer soon. John |

Would you prefer we call a storage battery a "voltaic pile" which was the original term used by Volta? I call my collection of web pages, a "web pile". It's not a capacitor. It's a "cazapitor" which goes "zap" when shorted. http://blogs.howstuffworks.com/2009/05/08/what-is-the-difference-between-a-battery-and-a-capacitor/ -- # Jeff Liebermann 150 Felker St #D Santa Cruz CA 95060 # 831-336-2558 # http://802.11junk.com # http://www.LearnByDestroying.com AE6KS |

No response there, but further research indicates that structural batteries and carbon composite electrochemical supercapacitors are different things. The batteries clearly involve oxidation and reduction at their electrodes, whereas the capacitors "operate by storing electrical charge along the double layer interface at each electrode".
