With the increasing of the electric vehicle's quantity(electric car,electric bike..etc), the traditional lead-acid battery is gradually replaced by lithium battery because of its low energy density, slow charging, heavy weight and bad circulation times. The production of lithium batteries can not be separated from a large number of lithium resources, then which country in the world own the most abundant lithium resources?
According to the United States Geological Survey (USGS) statistics, the global distribution of lithium resources, mainly in Chile, China, Argentina, Australia, Bolivia. 2016 global Lithium resources (proven and economically exploited) is 14.47 million tonnes, of which Chile ranked first in 7.5 million tonnes and China ranked second in 3.2 million tonnes.
So lithium as a metal element, what form does it exist in the nature? Chile, for example, has more than 50% of the world's lithium resources (proven resources), and Chile's lithium resources are concentrated in the northern part of the lake, the Salt Lake, which belongs to the magnesium sulfate subtype Salt Lake, the 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 of the Salt Lake lithium mainly, but constrained by the technology and mining costs show that at present, mainly in Xinjiang and Sichuan, pegmatite-type lithium ore and the basic feldspar granite-type lithium ore in Jiangxi as the main mining object.
But several other countries are also noteworthy. At present, the globally identified lithium ore resources (the sum of the solid mineral resources found in the survey work) are 47 million tonnes, of which both Argentina and Bolivia have identified resources of up to 9 million tonnes, only due to constraints or technical factors that have not been effectively developed
