Step 1: Material Required

1.Graphite rods

2.Tissue Paper

3. Aluminium Foil

Step 2: Wrap the Tissue Paper

Take a graphite rod wrap the tissue paper around the rod firmly such that rod is only open at the top.

Step 3: Wrap the Aluminium Foil

Wrap the aluminium foil around the rod such that there is no direct connection between the graphite rod and the aluminium foil

Step 4: Test the Continuity Between the Rod and Outer Foil

It's is much important to check the continuity between rod and outer foil so there would be no continuity between the rod and outer foil.

Step 5: Dissolve the Cell

Dissolve the rod/cell into the acidic solution/vinegar or rain water and this sol will act as a electrolyte.

Step 6: Your Battery Is Ready

Remove the battery from the solution. And check the voltage around it with the help of a multimeter and is your choice to connect it in series with more similar battery to increase the net voltage.
