Lithium is used to treat people who are suffering from bipolar disorder. While lithium cannot cure the disease, it eases the symptoms. It is also used to fuel torpedos, where blocks of lithium are melted by electric sparks before reacting with sulphur hexafluoride to produce heat. Lithium is used to make many different types of batteries, ceramics, enamels, dyes, rubber products and glass including lenses for glasses and telescopes. It is also often used in compounds such as lithium hydride, which inflates many life boats and balloons, or lithium deuteride, which used in the explosively active part of H-bombs.
