Construction of Mercury Cells
Construction of mercury cell include:
Anode zinc, cathode mercury oxide, and electrolyte (sodium or potassium hydroxide) are used in the construction of mercury cells. Given that mercury oxide is not a conductor, there may be a small quantity of graphite mixed in.
- Anode: Zinc Amalgamated with mercury
- Cathode: HgO mixed with graphite
- Electrolyte: Paste of KOH and ZnO
- Cell emf: about 1.35 V

Mercury Cell
Mercury Cell is a type of Primary Cell, which is non-rechargeable in nature, meaning it can only be used once before discarding it. The Mercury Cell is generally a small button-like structure and is mainly used in low-current devices such as watches, BIOS batteries on motherboards, and pacemakers. The Mercury cell has a potential of 1.35 Volts and is made by filling chemicals like mercury, mercuric oxide, carbon powder, zinc oxide, etc., into a steel container the size of a button.
In this article, we will learn about the mercury cell and its components and working of mercury cells and different types of mercury cells, and the advantages and applications of mercury cells.
