Lithium ore is one of the most important rare resources. Compared with rare earth, its application scope is more photovoltaic, which is also closely related to the development of science and technology. At present, lithium batteries made of lithium ore have become the mainstream batteries of various electronic products. Every year, a large number of lithium batteries are produced and applied to billions of mobile phones, laptops, tablets and other electronic products. Almost all electronic devices that need to be charged use lithium batteries.
