Tarix
Lithium was discovered by Johann Arfvedson in 1817 when he was analyzing minerals from the island of Uto in Sweden.
The pure metal was isolated the following year by both Swedish chemist William Thomas Brande and English chemist Sir Humphry Davy working independently.
In 1855, larger quantities of lithium were produced through the electrolysis of lithium chloride by Robert Bunsen and Augustus Matthiessen.
