Leclanchén.

/ləˈklɒnʃeɪ/

Etymology: < the name of Georges Leclanché (1839–82), French chemist.

Leclanché cell n. (also Leclanché battery) a primary cell invented by Leclanché that has a zinc cathode in contact with zinc chloride, ammonium chloride (in solution or as a paste) as the electrolyte, and a carbon anode in contact with a mixture of manganese dioxide and carbon powder.

1871 Chem. News 6 Oct. 166/2 I find that what I said about the Leclanché battery..has led to a false impression... It is used only on circuits of considerable resistance, and not much work, for which it is found very suitable.

1878 Encycl. Brit. VIII. 93/1 Good instances of this kind of action are furnished by the bichromate battery of Bunsen and the Léchanché [sic] cell, which occupy a sort of middle position between one and two fluid batteries.

1891 E. M. Caillard Electr. iv. 264 A form of Daniell's cell has been chiefly adopted in England, but the Leclanché is also excellent for telegraphic purposes.

1946 J. R. Partington Gen. & Inorg. Chem. xxix. 827 Manganese dioxide is used..as a depolariser in the Leclanché cell.

1971 L. T. Agger Introd. Electr. xi. 171 The dry form of the Leclanché cell, which was introduced towards the end of the last century, has generally replaced the wet Leclanché and is now by far the most commonly used primary cell.
