The world's lithium reserves rank among countries. The world's total lithium reserves are about 22 million tons.

The first lithium reserve was Chile. With a reserve of more than 19 million tons in the world, it is the second largest lithium producer with an output of 26,000 tons.

The second is Australia. The reserves are nearly 4 million tons. It is the largest producer of lithium.

The third is Argentina. The reserve is more than 2 million tons.

The fourth is China. Reserves1500,000 tons. The United States-750,000 tons, Zimbabwe-220,000 tons, Brazil-95,000 tons, Portugal-60,000 tons and more than ten countries.

There are three countries in the lithium triangle, Argentina, Bolivia and Chile, which together account for 63% of the world's lithium reserves. Lithium is an important metal for batteries and other electronic products, and it is a rechargeable lithium-ion battery for electric vehicle manufacturing and large-scale battery storage. The main lithium minerals of metallic lithium are spodumene, lepidolite and lepidolite. The world's lithium reserves rank first in the world, followed by Chile and Argentina, followed by Australia. In other words, the four major lithium mining countries are Bolivia, Argentina, Chile and Australia, and the lithium mines in the four major countries have the highest grade and the best quality. Chile has the highest proven reserves, followed by Australia, the United States and China. There are also lithium mines in Canada, Zimbabwe and Congo. However, it is not at the same level as the above four countries in scale and quality.
