Battery is actually a device which is used to convert the chemical energy into electrical energy. As there are two halves in the cell, the anode and the cathode should be used in the proper manner that is correct metals have to be chosen that the anions and the cat ions are in proper flow between the two half cells. The conduct between two cells is very essential for the conduct of electricity. The positively charged ions get attracted to the negative rod and the negatively charged ions get attracted towards positive charge. This has to be checked properly so that the electricity flows properly between the rods.
