With the continuous improvement of the amount of electric vehicles, the traditional lead-acid batteries due to low energy density, does not support fast charge, heavy weight, poor number of cycles and so on, is gradually being replaced by lithium batteries. A lot of lithium resources, then the world where the most abundant lithium resources?
Widely used 18650 lithium batteries
According to the United States Geological Survey (USGS) statistics, the global uneven distribution of lithium resources, mainly in Chile, China, the United States, the United States, the United States, the United States, the United States, the United States, Argentina, Australia, Bolivia and other countries .2016 global lithium has proven reserves (proven and has the value of economic exploitation) to 14.47 million tons, of which Chile to 7.5 million tons of reserves ranked first, China to 3.2 million tons ranking second.
In Chile, for example, Chile has more than 50% of the world's lithium resources (proven resources), and Chile's lithium resources are concentrated in the case of lithium, as a metal element, in what form of nature? Located in the northern area of the Atacama Salt Lake, the salt lake belongs to the magnesium sulfate subtype salt lake with an average lithium content of about 0.15% (lithium mass fraction).
China also has a wealth of lithium resources, and China's lithium resources are also concentrated in the Qaidam Basin and the Qinghai-Tibet Plateau salt lake lithium-based, but subject to technical and mining costs show that the current mainly in Xinjiang and Sichuan granite Pegmatite type lithium ore and is located in Jiangxi alkaline feldspar granite type lithium ore as the main mining object.
However, several countries are equally worth noting that the world's identified lithium resources (the sum of solid mineral resources found by exploration work) is 47 million tonnes, of which the amount of resources identified in Argentina and Bolivia Have reached 9 million tons, but because of the parties to limit or technical factors have not yet been effectively developed.
It can be seen that although China's lithium reserves are generally rich, but subject to mining technology and cost constraints, leading to China's long-term future will be a net importer of lithium carbonate, which may be China's lithium battery industry, the future development of negative impact The
