Differences between electrolytic cell and voltaic cell

1. It is a designed apparatus where electrolysis is carried out. It is an experimental set up or advice where chemical energy is converted into electrical energy.
2. This cell consists of a glass vessel or made up of any suitable plastic material, in which two electrodes are dipped into an electrolyte solution. Two electrodes  are dipped into the same or two different electrolyte solution in this type of cell.
3. Electric current is passed through the solution by connecting the two electrodes to a battery. Electric current is established only when the two electrodes are joined by a conducting wire.

 

4. In this cell, a chemical reaction occurs as a result of electric current. In this cell, electrical energy is produced as a result of chemical change or chemical reactions.
5. Anode is positive electrode and cathode is negative electrode. Anode is negative electrode here and cathode is positive electrode.
6. The redox- reaction is nonspontaneous and electrical energy is supplied to make reaction to occur. The redox-reaction is spontaneous and is responsible for the production of electrical energy.
7. The electrons are supplied by the external battery and enter through cathode and come out through anode.
