| Feature | Electrolytic Cell | Electrochemical Cell |
|---|---|---|
| Working Principle | Electrical energy is used to drive a non-spontaneous chemical reaction. | Chemical energy is converted into electrical energy through spontaneous redox reactions. |
| Direction of Electron Flow | From the external power source to the cell. | From the cell to the external circuit. |
| Electrolyte | Can be a liquid or molten substance. | Can be a liquid, solid, or gel substance. |
| Redox Reaction | Occurs due to the passage of electric current. | Occurs spontaneously without the need for an external power source. |
| Energy Conversion | Converts electrical energy into chemical energy. | Converts chemical energy into electrical energy. |
| Application | Electroplating, metal extraction, water electrolysis, etc. | Batteries, fuel cells, sensors, corrosion prevention, etc. |
