Electrochemistry is the branch of chemistry that deals with the study of the relationship between electricity and chemical reactions. In electrochemical reactions, electrons are transferred between species, leading to the generation of electric current. This field plays a crucial role in various applications such as batteries, fuel cells, corrosion prevention, and sensors. Researchers in electrochemistry study the mechanisms of redox reactions, the behavior of electrodes, and the development of new materials and technologies for energy storage and conversion.
