Things you might not know about
Lithium:
- Lithium is sometimes used as battery anode
material (high electrochemical potential) and lithium compounds are
used in dry cells and storage batteries
- Although it is a metal it is light enough to
float in water. It doesn't actually explode when put with water
unless you contain it in someway, but it does react with water
producing hydrogen and if a piece is dropped in water it will
skitter over the surface until it finally disappears.
- Just two companies produce most of the
world's lithium.
- More than 90% of lithium reserves are in
South America.
