In electrochemistry, overpotential is the potential difference (voltage) between a half-reaction's thermodynamically-determined reduction potential and the potential at which the redox event is experimentally observed. The term is directly related to a cell's voltage efficiency. In an electrolytic cell … See more The four possible polarities of overpotentials are listed below. • An electrolytic cell's anode is more positive, using more energy than thermodynamics require. • An electrolytic cell's See more • Electrolysis • Electrosynthesis See more Overpotential can be divided into many different subcategories that are not all well defined. For example, "polarization overpotential" can refer to the electrode polarization and the hysteresis found in forward and reverse peaks of cyclic voltammetry. … See more WebExcept for the need to take concentration overpotential into account in electroanalytical studies, it is an important factor for energy losses in electrochemical power sources (e.g., in -> batteries, fuel cells, etc.) and -> electrolysis (e.g., in electrochemical materials production, -> electroplating, etc.).
