difference between electrode n electrolyte....

If you put strips of two different metals into an appropriate electrolyte solution you are likely to find that a potential difference appears between the two strips. This system is a galvanic cell also known as battery.

The potential difference produced by an EMF associated with the chemical reactions between both the metals and the electrolyte.

The interface between each piece of metal and the electrolyte solution forms an electrode. Electrodes are always used in pairs. 

electrolyte is the solution in which the electricity is passed through the electrodes

Example

Cu Electrodes

Copper sulphate solution is electrolyte solution.
