uses

Lithium is effective in use for mental illnesses (likes bipolar disorder, depression, and schizophrenia). Lithium is also can used for others illnesses (likes headache, alcoholism, epilepsy, diabetes, and liver disease, etc).

The most important use of lithium is in rechargeable batteries for mobile phones, laptops, digital cameras and electric vehicles. Lithium is also used in some non-rechargeable batteries for things like heart pacemakers, toys and clocks.
