Key Facts & Information

BIOGRAPHY

  • Georges-Lionel Leclanché was born in Parmain, France, on October 9, 1839. His father, Léopold Leclanché, was a former student of Saint-Cyr and a friend of Ledru Rollin. His mother, Eugénie de Villeneuve, was the daughter of a member of the Convention.
  • Leclanché’s mother was reported that she was abused by police, who came to arrest her husband. Eugénie died a few months after giving birth to Maurice Leclanché, her second son.
  • Additionally, Leclanché’s family had a great friendship with Victor Hugo, who was a French novelist.
  • During the time Leclanché needed to start his education, his father was a politically and active cultured lawyer in the French government during the violent time in the country’s history. Because of several political issues, Leclanché and his father spent eighteen years away from Paris.
  • Therefore, Leclanché started his education in England and did not return to France until 1856, when Leclanché decided to enter the École Centrale Imperiale des Arts et Manufactures to study metallurgy.
  • Leclanché became more interested in analytical and industrial chemistry. In 1860, after graduating, he started working as a laboratory manager in a railway company that was manufacturing lead salts.

THE LECLANCHÉ CELL

  • In the set-up of a system electrical transmission, the current batteries were not compatible, making him start his research in the laboratory on the pile of copper carbonate. However, due to the pressure of the second empire, Leclanché was exiled to Belgium, where he reunited with Victor Hugo’s family.
  • Leclanché established a small laboratory to continue his research about batteries. On January 8, 1866, Leclanché was granted French patent no. 71865, for his significant advancement in the technology of the primary electrochemical cell.
  • The primary electrochemical cell is typically called a battery. It is an electrochemical cell that generates electric current by several chemical reactions at the cell’s two electrodes, the cathode and anode.
  • The battery that Leclanché invented was called the Leclanché cell. The Leclanché cell is a primary electrochemical cell that is handy for sporadic use, with a positive anode of zinc that encompasses a mixture of manganese dioxide and porous powdered carbon in a pot.
  • The pot and the negative zinc terminal remained in a container that holds the ammonium chloride solution. The electromagnetic force of this cell is nearly 1-4 volt. Leclanché’s battery was also called a zinc-carbon battery.
  • It uses an alternate type of cell than its antecedents. Leclanché utilized zinc and carbon-manganese dioxide mixture for his terminals rather than using lead. He also used ammonium chloride rather than using sulfuric acid, which is referred to as the electrolyte.
  • The electrolyte is the substance that helps produce an electrically conducting solution when dissolved in a polar solvent such as water.

HOW DOES THE LECLANCHÉ CELL WORK?

  • The Leclanché cell has three types- zinc or the carbon cathode, zinc chloride or the ammonium chloride electrolyte reinstated by zinc chloride, and alkaline manganese or the ammonium chloride terminal that is displaced by potassium hydroxide.
  • The process that generates the Leclanché cell’s power begins when zinc particles on the surface of the anode oxidize. It is when the zinc particles surrender their valence electrons (valence electron is the outer shell of an electron or the negatively charged particles that is associated with an atom) that results in the positively charged particles.
  • This flow of electrons surrounds the electric current. After passing through the entire circuit, the electrons enter the carbon rod or the cathode, they attach with water and manganese dioxide, which further reacts to produce negatively charged hydroxide ions manganese oxide.
  • The whole process is supported by a secondary reaction, where the negative hydroxide ions react with the positive ammonium ions in the electrolyte of ammonium chloride to produce molecules of water and ammonia.

LECLANCHÉ CELL PRACTICAL USE

  • Leclanché’s invention, the Leclanché cell, was utilized widely in telegraphy, electric bell, and signaling work. Also, it was used where the intermittent and low current of electricity is needed.
  • This work of Leclanché became instrumental and significantly advantageous in the early years of the development of telephones.

LATER IN LIFE

  • After developing and inventing the Leclanché cell, he started his company to manufacture and continue the development of the battery cell until his death from throat cancer on September 14, 1882, in Paris, France, at the age of forty-three years old.
