In cell carbon rods are not used it is in reality graphite or carbon 14 atom it is a non metel and an allotrophe of carbon means it consists of carbon but the atomic structure of carbon is different in it. So carbon is a non metel which is a bad conductor of electricity but its allotrophe graphite is a good conductor of electricity

Carbon rods are commonly used in various types of cells, including dry cells, electrolytic cells, and voltaic cells, despite being a poor conductor of electricity. This may seem contradictory at first, but there are several reasons why carbon rods are chosen for these applications. Let's explore these reasons in detail:


- Cells involve electrochemical reactions, where chemical energy is converted into electrical energy.
- The carbon rod serves as an electrode in the cell, facilitating these reactions.
- It acts as the positive electrode (anode) in some cells, such as dry cells, and the negative electrode (cathode) in others, such as electrolytic cells.
- The carbon rod's role is to provide a surface for the necessary electrochemical reactions to occur.


- Carbon rods used in cells are typically made of graphite, which has a porous structure.
- The pores in the graphite allow for the movement of ions and electrons, essential for the functioning of the cell.
- The porous nature of carbon rods enhances their electrochemical activity, making them suitable for use in cells.


- Carbon rods exhibit excellent stability and durability under the conditions present in cells.
- They have a high melting point and can withstand the chemical reactions taking place in the cell without deteriorating.
- Carbon rods also have a relatively low reactivity, reducing the likelihood of unwanted reactions occurring during cell operation.


- Carbon is an abundant and relatively inexpensive material.
- Using carbon rods in cells helps keep the production costs of these devices low.
- This cost-effectiveness makes carbon rods a practical choice for various cell applications.

Overall, while carbon is indeed a poor conductor of electricity, its suitability as an electrode material in cells is due to its electrochemical properties, porous structure, stability, durability, and cost-effectiveness. These factors outweigh its lower conductivity and make carbon rods an essential component in various types of cells.
