Working Electrodes

Abstract

In electrochemistry an electrode is the entire assembly of an electronic conductor in intimate contact with an ionic conductor. The electronic conductor can be a metal, or a semiconductor, or a mixed electronic and ionic conductor. The ionic conductor is usually an electrolyte solution; however, solid electrolytes can be used as well. The term “electrode” is also used in a technical sense, meaning the electronic conductor only. If not specified otherwise, this meaning of the term “electrode” is the subject of the present chapter.
