An electrolytic cell is characterized by the use of an external power source to drive a non-spontaneous chemical reaction. It consists of two electrodes: the anode, where oxidation occurs, and the cathode, where reduction takes place. The cell contains an electrolyte solution that facilitates the movement of ions, and it typically operates with a flow of electric current, resulting in the decomposition of compounds, such as in electrolysis. Overall, electrolytic cells are essential in processes like electroplating and the production of chemicals.

A galvanic cell can become an electrolytic cell by applying an external voltage that is of opposite polarity to the cell's spontaneous voltage. This external voltage can overcome the natural tendency of the cell to generate electricity and drive a non-spontaneous chemical reaction in the reverse direction, converting it into an electrolytic cell.
In an electrolytic cell, an external power source is needed to drive a non-spontaneous redox reaction, while in a voltaic cell, the redox reaction is spontaneous and generates electric energy. In an electrolytic cell, the anode is positive and the cathode is negative, whereas in a voltaic cell, the anode is negative and the cathode is positive.
