I am curious about the use of terms in the article “Batteries and Electrochemical Capacitors” by Héctor Abruña, Yasuyuki Kiya, and Jay Henderson (Physics Today, December 2008, page 43 ). When I went to college many years ago, the words “anode” and “cathode” referred to function and not polarity. Electrons always come out of the anode. When a battery switches from charge to discharge, the anode switches from positive to negative terminal (or vice versa). Are the terms no longer used that way?
