electrochemical cell

An electrochemical cell is a device that converts chemical energy into electrical energy through chemical reactions. It typically consists of two different materials called electrodes submerged in an electrolyte solution. These electrodes undergo chemical reactions that produce an electric current, which can power devices or be stored for later use. The cell has a positive terminal (cathode) and a negative terminal (anode), with electrons flowing from one to the other through an external circuit. This process is the basis for batteries and many electrochemical processes, enabling the generation or storage of electrical energy from chemical reactions.
