Anode vs. Cathode: Understanding the Key Differences
In batteries, the anode is the negative electrode, while in electroplating, the anode is the electrode that is coated with the metal that is being deposited onto the substrate. In corrosion protection, anodes are used to protect metal structures from corrosion by providing a sacrificial metal that will corrode in place of the protected metal.
