Abstract: Lithium is one of the most important minerals in the emerging industry, and its role in the development of national economy is becoming more and more important.The resources of global lithium are rich enough to guarantee the supply of resources and meet the long-term needs of economic and social development.With more and more attention paid in the lithium industry, there are more and more projects of the global lithium exploration and development so that the reserves of lithium increased significantly.Global lithium production is highly concentrated, showing the situation of oligopoly.At the same time, driven by the rapid growth of new energy vehicles, global lithium demand rapid growth.In the future, with the gradual depletion of global fossil energy, lithium applications in the fields of nuclear fusion power plants and power cars will increase so quickly that the global demand of lithium will grow rapidly.The global lithium supply is sufficient.In future, this situation may occur that global lithium supply is far greater than the demand.By then, Chile, Argentina, Australia and the United States may become a major exporter of lithium products.
