Question

What are the advantages of dry cells?​

Answer 1

In 1887, Carl Gassner invented the dry cell battery, the more visible of the two battery types, by combining zinc and carbon. All dry cell batteries have a metal electrode or graphite rod covered by an electrolyte paste, all within in a metal container. In an acidic dry cell, the electricity-generating reduction reaction typically takes place in a paste comprised of ammonium chloride (NH4Cl) and manganese dioxide (MnO2). In a longer-lasting alkaline dry cell, potassium hydroxide (KOH) or sodium hydroxide (NaOH) reacts with manganese dioxide. Other batteries might use silver oxide (Ag2O), mercuric oxide (HgO) or nickel/cadmium. Dry cells can be either primary or secondary cells.

Answer 2

Answer:

1. The electrolyte used in dry cell is relatively not so harmful to the environment.

2. It is light and small in size and can be transported from one place to another.
