Hint: Galvanic cell is an electrochemical cell , in which redox reaction occurs and due to which it gains electricity . It consists of two half cells ,in which one half cell contains metal $A$ and other half cell contains $B$ metal .

Complete answer:
In galvanic cells the electric current generated by the transfer of electrons through redox reaction.
Some simple galvanic cells contain only one electrode and complex one contain two electrodes. Galvanic cell which is made up of two electrodes. In which one is cathode which is positively charged and another is anode which will be negatively charged. The reduction reaction will occur at cathode and oxidation reaction will occur at anode. These two electrodes are immersed in the salt of solutions of its own ions. These two are joined by a salt bridge. This bridge helps to prevent the metals solutions from getting mixed and also the transfer of electrons in the chemical reactions takes place through it . a salt bridge contains an inert electrolyte like potassium sulphate . This bridge actually completes the whole circuit and a voltmeter is attached with both the electrodes which are made up of different metals .
The voltage in the galvanic cell occurs due to difference in the potential of two electrodes present . now we need to give one example of galvanic cell whose voltage is more than $2.5V$
$L{i^ + }$ / $Li$ cell gives potential of $3.05V$ .

Lithium is the best material for energy storage. It is light weighted portable applications and also easy in transportation. Lithium batteries provide highest gravimetric density . Also a fuel cell is also a galvanic cell .
