The domestic market share of battery-grade lithium carbonate in Tianqi lithium industry is about 54%. The main assets of Tianqi Lithium Industry are mainly concentrated in the Greenbush mine in Western Australia and the Atacama Salt Lake in Chile. In terms of market value, the market value of Tianqi lithium industry has reached 2.910.44 billion yuan, ranking first among the six listed companies in China. The second place is Ganfeng Lithium Industry, with a market value of 28.605 billion yuan. These two companies are far ahead of other listed lithium mining companies in market value and income. Tianqi Lithium Industry is the leading enterprise of new energy materials in China and the main supplier of new energy for lithium batteries in China. In China lithium battery industry, Tianqi's technology and comprehensive competitiveness are undoubtedly the first in China. The main business scope of Tianqi lithium industry is actually the research and development, production and sales of lithium series products. The main sales products of Tianqi Lithium Industry are metallic lithium, battery-grade and industrial-grade lithium carbonate, battery-grade and industrial-grade anhydrous lithium chloride, battery-grade and industrial-grade lithium hydroxide, etc.
As a stable metal substance, lithium is widely used, and the lithium material circulating in the market at present is only the tip of the iceberg. The range of action of lithium is not limited to new energy batteries, and it can also give full play to its characteristics in other aspects. Lithium is a silvery white metallic element, which is soft and has the lowest density. It was discovered by Alfred Johnson. Lithium is a metal with strong metal activity, which can be used in atomic reactors, light alloys and batteries. In nature, it mainly exists in the form of spodumene, lepidolite and hectorite, and needs to be stored in the air. Dry sodium carbonate powder should be used to put out fires caused by lithium. In nature, it mainly exists in the form of spodumene, lepidolite and hectorite ore. The natural reserve of lithium in the crust is 1 1 10,000 tons, and the exploitable reserve is 4 1 10,000 tons.
The main industrial use of lithium in the early days was to use lithium stearate as a thickener for lubricants. Lithium-based grease has high water resistance, high temperature resistance and good low temperature performance. If you add lithium lubricant to some parts of the car once, it will be enough until the car is scrapped. In metallurgical industry, lithium can react strongly with oxygen, nitrogen, chlorine, sulfur and other substances, and play the role of deoxidizer and desulfurizer. In the process of copper smelting, adding1100000 ~1100000 lithium can improve the internal structure of copper and make it more compact, thus improving the conductivity of copper. Lithium can remove harmful impurities and gases when casting high-quality copper castings. Among the high-quality special alloy steels needed in modern times, lithium is the most ideal impurity removal material. 1kg lithium can release 42998kJ of heat after combustion, so lithium is one of the best metals used as rocket fuel. The energy released by 1kg lithium through thermonuclear reaction is equivalent to burning more than 20,000 tons of high-quality coal. If lithium or lithium compounds are used as the driving force of rockets, missiles and spaceships instead of solid propellants, not only the energy and burning rate are high, but also the specific impulse is extremely high, and the effective load of rockets directly depends on the specific impulse. If lithium is added in glass manufacturing, the solubility of lithium glass is only1100 of that of ordinary glass (there is about one tenth of glass in each cup of ordinary hot tea). After adding lithium, the glass becomes "never soluble" and can resist acid corrosion. Pure aluminum is too soft. When a small amount of lithium, magnesium, beryllium and other metals are added to aluminum and melted into alloys, it is both light and extremely hard. Using this alloy as an airplane can reduce the weight of the airplane by two thirds, and a lithium airplane can be carried by two people. Lithium-lead alloy is a good antifriction material.
