WebMar 9, 2024 · Let us take an overview of the dry cell battery: The outermost part is a Zinc cylinder which acts as the anode. This anode is filled inside with a moist paste of N H 4 C l & Z n C l 2 The graphite rod inside acts as a cathode. A paste of manganese dioxide and carbon powder surrounds the cathode. WebThe zinc container becomes thinner as the cell is used, because zinc metal is oxidized to zinc ions. When the zinc case thins enough, zinc chloride begins to leak out of the battery. The old dry cell is not leak-proof and becomes very sticky as the paste leaks through the holes in the zinc case.
WebA thin zinc cylinder serves as the anode and it undergoes oxidation: +2Zn (s) -----> Zn + 2e-This dry cell "couple" produces about 1.5 volts. ( These "dry cells" can also be linked in series to boost the voltage produced). In the alkaline version or "alkaline battery", the
