A voltaic cell, also known as a galvanic cell, is a device that converts chemical energy into electrical energy through spontaneous redox reactions. It consists of two electrodes, an anode and a cathode, immersed in an electrolyte solution. The anode undergoes oxidation, releasing electrons, while the cathode undergoes reduction, accepting electrons. This flow of electrons generates an electric current. The basic components of a voltaic cell include the two electrodes, the electrolyte, and a salt bridge that maintains electrical neutrality. Common examples of voltaic cells are found in batteries, such as alkaline batteries and lithium-ion batteries, which power various electronic devices.
