Difference between Electrochemical Cell and Electrolytic Cells.

Electrochemical Cell Electrolytic Cell
It converts chemical energy into electrical energy.It converts electrical energy into chemical energy.
It is based upon the redox reactions which are spontaneous.The redox reactions are non-spontaneous and take place only when energy is supplied.
The chemical changes occurring in the two beakers are different.Only one chemical compound undergoes decomposition.
Anode (-ve) - Oxidation takes place.Anode (+ve) - Oxidation takes place.
Cathode (+ve) - Reduction takes place.Cathode (-ve) - Reduction takes place.
