Leclanche's "wet cell" (as it was popularly called) was the forerunner to the world's first widely used battery, the Zinc-carbon battery
Zinc-carbon battery
A zinc–carbon dry cell or battery is packaged in a zinc can that serves as both a container and negative terminal. It was developed from the wet Leclanché cell . The positive terminal is a carbon rod surrounded by a mixture of manganese dioxide and carbon powder. The electrolyte used is a paste of...
