Georges Leclanché

Georges Leclanché (born October 9, 1839 in Parmain , Département Seine-et-Oise , † September 14, 1882 in Paris ) was a French physical chemist .

George Leclanché began his studies in England, but returned to France to enter the École Centrale des Arts et Manufactures (now École Centrale Paris ), where he graduated in 1860.

Georges Leclanché invented the Leclanché element , which is considered the forerunner of today's dry batteries and which he patented in 1866. Leclanché received a bronze medal at the world exhibition in Paris that same year. The battery was immediately introduced by the Belgian railways and the Belgian telegraph. Leclanché continuously improved the battery and in 1876 he was able to turn the electrolyte into a gel by adding starch.

In the meantime he had moved to Paris, where he married Gabrielle Clementine-Lannes in 1873 and had two children.

The improved version of the Leclanché element consists of a zinc beaker filled with an ammonium chloride solution thickened with gelatine . A carbon electrode, which is coated with powdered brownstone , dips into this cup .
