Leclanché cell

In 1866 he invented the Leclanché cell, one of the first electrical batteries and the forerunner of the modern dry cell battery. It comprised a conducting solution (electrolyte) of ammonium chloride with a negative terminal of zinc and a positive terminal of manganese dioxide.

Leclanche's "wet cell" (as it was popularly called) was the forerunner to the world's first widely used battery, the Zinc-carbon battery.
