Two electrodes in electrolyte solutions
Mg(s) Apex baby
A voltaic battery is also known as a voltaic pile, which is a set (or pile) of galvanic cells linked together in series to create a larger voltage than could be generated by a single galvanic cell. Therefore a voltaic cell would simply be one element of the pile which is also one galvanic cell.
The build-up of reaction products at the electrodes can slow down the reaction rate and eventually stop the cell from producing an electric current. Depletion of reactants in the cell can lead to a lack of ions available for the redox reactions to occur, causing the cell to no longer generate electricity.

Two electrodes in electrolyte solutions
In a galvanic cell with silver and nickel electrodes, nickel is oxidized at the anode. During oxidation, nickel atoms lose electrons and become Ni2+ ions, contributing to the flow of electrons in the cell. Silver acts as the cathode where reduction reactions take place.

In a galvanic cell made with silver and nickel electrodes, the nickel electrode undergoes oxidation as it loses electrons, which travel through the external circuit to the silver electrode where reduction occurs. This flow of electrons generates an electric current in the cell.
