Anode
The electrode where electrons are lost (oxidized) in redox reactions.
The electrode of an electrolyte cell at which oxidation occurs, electrons flow away from the anode in the external circuit, it is usually at the electrode that corrosion occurs and metal ions enter solution.
During discharge, the negative electrode of the cell is the anode.
During charge, the situation reverses and the positive electrode of the cell is the anode.
