The field of electrochemistry is concerned with the relationship between electrical potential and chemical reactions. Broadly speaking, this includes processes where a chemical reaction results in an electrical change (such as in a battery) or when a non-spontaneous chemical reaction is triggered by a change in electrical potential (via electrolysis). In materials science, electrochemical methods are used to study the properties of materials.
The most common electrochemical method for the study of materials is cyclic voltammetry, which is performed with a potentiostat such as the Ossila Potentiostat. In cyclic voltammetry, the potential across a three electrode cell is linearly cycled, which causes the chemical to either gain or lose an electron. The resulting change in current is measured and plotted against the applied potential to reveal intrinsic properties of the material in question. For more information and practical advice on electrochemistry and performing cyclic voltammetry, please refer to the guides below.
