A standard CV experiment uses a reference electrode, working electrode, and counter electrode. This combination is sometimes referred to as a ‘three-electrode setup’ [5–7]. An electrolyte is usually added to the sample solution to ensure sufficient conductivity. The solvent, electrolyte, and material composition of the working electrode determine the potential range that can be accessed during 42 Electrochemical Characterisations the experiment. The electrodes are immobile and sit in unstirred solutions during CV.

If a reversible peak is observed, thermodynamic information in the form of a half-cell potential E 01/2 can be determined. If waves are semi-reversible ( iap / icp is close but not equal to 1) it may be possible to determine even more specific information. If waves are non-reversible it is, in general, not possible to determine the thermodynamic potential E 01/2 with CV (when it is possible the system usually contains equal quantities of the analyte in both oxidation states). The redox couple could be irreversible because of a subsequent chemical process; a common example of this phenomenon is a transition metal complex changing its coordination sphere geometry after an electron is transferred to or from it.
