Electrodes

Electrodes are conductive materials that facilitate the transfer of electrons between an external circuit and a substance (such as an electrolyte or a semiconductor) in electrochemical cells, batteries, capacitors, and other electronic devices. The primary function of electrodes is to provide an interface for chemical reactions to occur in processes such as oxidation-reduction (redox) reactions. There are two main types of electrodes: 1. **Anode**: This is the electrode where oxidation occurs.
