Electrochemistry

Electrochemistry is defined as the branch of chemistry that examines the phenomena resulting from combined chemical and electrical effects that cause electrons to move. This movement of electrons is called electricity, which can be generated by movements of electrons from one element to another in a reaction known as an oxidation- reduction ("redox") reaction. A reaction is classified as oxidation or reduction depending on the direction of electron transfer. The principles of cells are used to make electrical batteries. In science and technology, a battery is a device that stores chemical energy and makes it available in an electrical form. Electrochemistry is also vital in a wide range of important technological applications. For example, batteries are important not only in storing energy for mobile devices and vehicles, but also for load levelling to enable the use of renewable energy conversion technologies. This field covers

Electrolytic processes - Reactions in which chemical changes occur on the passage of an electrical current.

Galvanic or voltaic processes: Chemical reactions that results in the production of electrical energy.
