Electrochemistry is a branch of chemistry that studies the interaction between electrical energy and chemical changes. It involves the movement of electrons in chemical reactions and the conversion of chemical energy into electrical energy, and vice versa. Electrochemical research encompasses a wide range of topics, including batteries, fuel cells, corrosion, sensors, and electroplating. It plays a crucial role in many industries, such as energy storage, environmental monitoring, and materials science. Researchers in the field of electrochemistry aim to understand and manipulate these processes to develop new technologies and improve existing ones.
