The Leclanché cell, developed in 1866 by French engineer Georges Leclanché, is one of the earliest types of electrochemical cells. It features a simple design consisting of a zinc anode, which serves as the negative electrode, and a carbon cathode surrounded by a mixture of manganese dioxide and carbon, acting as the positive electrode. The cell’s electrolyte is typically a solution of ammonium chloride (NH₄Cl) and sometimes zinc chloride (ZnCl₂), facilitating ion movement between the electrodes. When activated, the zinc anode undergoes oxidation, releasing electrons that flow through an external circuit to the carbon cathode, where reduction occurs with ammonium ions. The cell generates a nominal voltage of around 1.5 volts and is commonly used in low-drain applications like early flashlights and doorbells. Although it has a relatively short lifespan and has been largely replaced by more efficient batteries, the Leclanché cell remains an important educational tool for demonstrating fundamental electrochemical principles
