Difference Between Galvanic and Electrolytic Cells

Galvanic cells and electrolytic cells are two types of electrochemical cells and have several differences:

• Galvanic Cells:
  • Convert chemical energy into electrical energy.
  • Spontaneous redox reactions occur.
  • Anode is negative, and cathode is positive.
  • Used in batteries.
• Electrolytic Cells:
  • Convert electrical energy into chemical energy.
  • Non-spontaneous redox reactions occur.
  • Anode is positive, and cathode is negative.
  • Used in electroplating, electrolysis, etc.

In summary, the main difference lies in the direction of energy conversion and the spontaneity of the reactions.
