What is a Dry Cell?
A dry cell is a type of electrochemical cell, commonly used as a portable source of electric power. It is called a “dry cell” because it does not contain liquid electrolytes, unlike wet cells such as car batteries. Dry cells are commonly used in household items like flashlights, remote controls, and portable electronic devices.
It consists of a cathode (positive electrode) made of a mixture of manganese dioxide and carbon powder, an anode (negative electrode) usually composed of zinc, and a moist paste or gel-like electrolyte. The components are housed in a zinc container, and a separator prevents direct contact between the cathode and anode.
Dry Cell was invented by Carl Gassner, a German scientist, in 1888. Gassner’s design improved upon earlier battery technologies by using a paste electrolyte instead of a liquid one, making the battery more portable and less prone to leakage.
Dry Cell Definition
Dry cell is an electrochemical cell that generates electrical energy through a chemical reaction without using a liquid electrolyte.

Dry Cell
Dry Cell is a portable electrochemical cell invented by German scientist Carl Gassner in 1888. Unlike traditional wet cells, a dry cell features a paste or gel-like electrolyte, eliminating the risk of leakage and enhancing portability. It is commonly used in household essentials such as flashlights and remote controls. Dry Cells are reliable and convenient energy storage devices.
