LECLANCHE CELL, 1896

The cell was invented by Georges Leclanche' in 1866, it is the forerunner of modern Zinc Carbon dry cells. In the centre is a porous cylinder filled with Manganese Dioxide and in the centre of this is a carbon rod. Outside of the cylinder is a zinc rod. The jar would normally be filled with Ammonium Chloride. The Positive terminal is the carbon rod and the zinc is negative. The voltage obtained is 1.5 Volts.

Georges Leclanché (1839 - 1882) was a French electrical engineer chiefly remembered for his invention of the Leclanché cell; one of the first modern electrical batteries and the forerunner of the modern dry cell battery.
The original form of the cell used a porous pot. This gave it a relatively high internal resistance and various modifications were made to reduce it. These included the "Agglomerate block cell" and the "Sack cell".
