LeclanchéZellen
LeclanchéZellen refers to a type of wet cell battery invented by Georges Leclanché in 1866. It is a primary cell, meaning it is designed for single use and cannot be recharged. The original Leclanché cell consisted of a zinc anode and a carbon cathode. The electrolyte was a solution of ammonium chloride, and the cathode was surrounded by a paste of manganese dioxide and carbon powder. The manganese dioxide acted as a depolarizer, preventing the buildup of hydrogen gas at the cathode, which would otherwise reduce the cell's efficiency.
When the cell is connected to an external circuit, zinc is oxidized at the anode, releasing electrons.
The design of the Leclanché cell has evolved over time. Dry cell versions, where the electrolyte is
