Leclanché cell

(ləˈklɑːnʃeɪ)
n
(Electrical Engineering) electrical engineering a primary cell with a carbon anode, surrounded by crushed carbon and manganese dioxide in a porous container, immersed in an electrolyte of aqueous ammonium chloride into which the zinc cathode dips. The common dry battery is a form of Leclanché cell

However, it took some further 70 years beyond the date of his discovery for practical batteries to become widely available: the Pb-acid battery by Plante, the Leclanche cell and the Ni-Fe or Ni-Cd batteries by Edison and Jungner.
Both cells employ zinc and manganese dioxide as electrode material, but in contrast to the Leclanche cell, the alkali-manganese cells use highly concentrated KOH solution containing ZnO as the electrolyte.
