Leclanché was born in 1839 in Parmain (Seine-et-Oise), France, the son of Léopold Leclanché and Eugenie of Villeneuve. Due to the political situation in France, and because his father was a former minister, his parents, also friends of the writer
After the fall of
After his death, his brother Maurice took over the business and his son Max also continued to improve and to commercialise his invention.
Leclanché cell
In 1866 he invented the
Leclanché's "wet cell" (as it was popularly called) was the forerunner to the world's first widely used battery, the zinc–carbon battery.
In 1876, Leclanché jellifies the electrolyte of his cell by adding starch to the ammonium chloride, making his cell more portable.[4]
Leclanché company
The Leclanché factory successfully developed until the beginning of the 20th century when it encountered the concurrence of many new producers such as the Wonder cells (founded in 1914). The enterprise changed several times of hands, was bought by the Fulmen battery company and finally by the CGE group.
The name Leclanché is presently used by a company based in Yverdon in Switzerland and founded in 1909. In 2006, this company acquired the German society Bullith which became the "Leclanché Lithium GmbH", based today in Willstätt (Baden-Württemberg in Germany).
