Lithium batteries are divided into lithium batteries and lithium ion batteries. Cell phones and notebook computers use lithium-ion batteries, which are commonly known as lithium batteries. Real lithium batteries are rarely used in daily electronic products because of their high risk.

Lithium batteries are widely used in energy storage power systems such as water power, thermal power, wind power and solar power plants, as well as power tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace and other fields. At present, lithium batteries have gradually expanded to the fields of electric bicycles and electric vehicles.
