Due to the political situation in France, and because his father was a former minister, his parents, also friends of the writer Victor Hugo, decided to take the way of exile in the United Kingdom.
After the fall of Napoléon III, he came back in France in Paris where he became associated with Ernest Barbier to found the cells factory "Leclanché-Barbier".
[4] 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.
In 2006, this company acquired the German society Bullith which became the "Leclanché Lithium GmbH", based today in Willstätt (Baden-Württemberg in Germany).
