5 Faure, Camille Alphonse
SUBJECT AREA: Electricity[br]b. 21 May 1840 Vizille, Franced. September 1898[br]French chemist, inventor of an improved method of preparing the plates for Planté lead-acid secondary cells.[br]After technical training at the Ecole des Arts et Métiers at Aix, Faure was employed superintending the erection of factories in France and England. These included the Cotton Powder Company plant in Faversham for the manufacture of the explosive Tonite invented by Faure. He also invented distress signals used by the merchant navy. It was between 1878 and 1880 that he performed his most important work, the improvement of the Planté cell. Faure's invention of coating the lead plates with a paste of lead oxide substantially reduced the time taken to form the plates. Their construction was subsequently further improved by Swan and others. These developments appeared at a particularly opportune time because lead-acid secondary cells found immediate application in telegraphy and later in electric lighting and traction systems, where their use resulted in reduced costs of providing supplies during peak-load periods. In his later years Faure's attention was directed to other electrochemical problems, including the manufacture of aluminium.[br]Bibliography1881, "Sur la pile secondaire de M C.Faure", Comptes rendus 92:951–3 (announcing his cell).11 January 1881, British patent no. 129 (Faure's improvement of the Planté cell).Further ReadingElectrician (1882) 7:122–3 (describes the Faure cell).G.Wood Vinal, 1955, Storage Batteries, 4th edn, London (describes later developments).GWBiographical history of technology > Faure, Camille Alphonse

6 Planté, Raimond Louis Gaston
SUBJECT AREA: Electricity[br]b. 22 April 1834 Orthez, Franced. 21 May 1889 Paris, France[br]French physicist and inventor of a secondary electric cell from which was developed the widely used lead-acid storage battery.[br]After a scientific training at the Conservatoire des Arts et Métiers, Planté obtained an appointment as a Laboratory Assistant to Becquerel. Later, when he was employed as a chemist in the Parisian electroplating firm of Christofle et Cie, he carried out investigations into polarization in electrical cells, which led to his discovery of the lead-acid accumulator in 1859. This cell, with lead plates in an electrolyte of dilute sulphuric acid, had the characteristics of a storage device for electrical energy. Its performance was improved considerably if it was repeatedly charged and discharged, the active material being formed electrochemically from the lead of the plate itself. At the time of its discovery the Planté cell had little practical application and it was not until satisfactory dynamos were introduced that its commercial exploitation was possible. The cell was improved by Faure and later by Swan and others. The lead-acid cell became considerably important in the early days of electricity supply and later for electric traction and automobile use. The results of Planté's researches were communicated to the Academy of Sciences and published in various scientific periodicals. He devoted the last few years of his life to the study of atmospheric electricity.[br]Principal Honours and DistinctionsChevalier de la Légion d'honneur 1881.
