Camille Alphonse Faure
Camille Alphonse Faure (21 May 1840 – 14 September 1898) was a French chemical engineer who in 1881 significantly improved the design of the lead-acid battery, which had been invented by Gaston Planté in 1859. Faure's improvements greatly increased the capacity of such batteries and led directly to their manufacture on an industrial scale.[1]
Biography
He was born at Vizille and trained at the Ecole des Arts et Métiers at Aix.[2] From 1874 until about 1880, he worked as a chemist at the new factory of the Cotton Powder Company at Uplees, Faversham, Kent, England.[3] While there, he and the factory manager, George Trench, took out patents for Tonite (a new high explosive) (1874), and an improved dynamite detonator (1878).[4]
In 1880, Faure patented a method of coating lead plates with a paste of lead oxides, sulphuric acid and water, which was then cured by being gently warmed in a humid atmosphere. The curing process caused the paste to change to a mixture of lead sulphates which adhered to the lead plate. During charging the cured paste was converted into electrochemically active material (the "active mass") and gave a substantial increase in capacity compared with Planté's battery.[5] This was a significant breakthrough that led to the industrial manufacture of lead-acid batteries, as now used for starting motor cars.
Towards the end of his life Faure was granted further patents,[6] among them ones for the manufacture of aluminium alloys and improvements to hot air engines and motor vehicle steering mechanisms.
