The core technology of Tian Qi lithium industry "exaggerated"?

The day before the Li-Qi lithium industry was "alleged" patent technology is invalid (see this newspaper August 20, "90 times times the shadow of the price-earnings ratio: GE lithium is" accused of "the lithium tin industry patent is invalid), its exclusive ore method directly to the production of battery-grade lithium carbonate is not true.　　Reporters interviewed industry experts that Tian Qi Li's prospectus said that it has "direct use of ore to extract battery-grade lithium carbonate core technology, is the only one in the world to use ore lithium-ion integrated production of battery-grade lithium carbonate manufacturers", there are many questions. The core technology selling point as Gan Feng Lithium industry (002460. SZ) of the shadow stocks, Tian Qi lithium industry has been placed high expectations. , the first day of the company's IPO soared by about 186% per cent, becoming the new shares that showed the second-most-than-Asian process this year.　　In the days when new energy has been renewed, the lithium-ion industry has become a favorite of speculation.　　The National securities report of August 23 said that Tian Qi lithium is a "technical advantage to control the market share of the model", because "the company exclusive possession of the ore method directly to the production of battery-grade lithium carbonate and anhydrous lithium chloride process, with obvious cost advantages."　　Citic Investment also believes that the Tian Qi lithium industry, the "lithium industry leader, with the new energy dances," the reason is because of "scale + brand + technology", the ore method directly to make battery-grade lithium carbonate for its selling point.　　The first day rose 186% of Gan Feng Li's selling point is to master the core technology of Brine direct lithium chloride, and Tian Qi lithium industry is repeatedly mentioned in the prospectus "exclusive ore method directly to the production of battery-grade lithium carbonate process." Company Prospectus pointed out that "the company is the only domestic industry with lithium pyroxene direct production of industrial-grade lithium carbonate, battery-grade lithium carbonate, anhydrous lithium chloride and lithium hydroxide production process enterprises, according to market demand flexibility to adjust the production of lithium products, thus greatly reducing production costs." "In particular, battery-grade lithium carbonate core technology," because the company has mastered the direct use of ore extraction battery-grade lithium carbonate core technology, is the only one in the world to use ore lithium-ion production of battery-grade lithium carbonate manufacturers, technical advantages are obvious. At the same time, the company also stressed that the China Nonferrous Metals Industry Association: Tian Qi Lithium industry is the largest lithium production enterprises in China, is the leading technology in lithium industry, the largest and most comprehensive competitive enterprises, in the world's exclusive possession of the same industry in the production of battery-grade lithium carbonate and battery-grade lithium chloride and other core technology.　　"is the core technology exclusive?" In the end, what kind of technology does the ore method produce battery grade lithium carbonate? The integration of lithium ores to produce battery grade lithium carbonate What is the concept?　　The direct use of ore to extract battery grade lithium carbonate is not the tin qi industry unique?　　Reporter investigation found: Lithium carbonate is the most used in the lithium industry, the basic products, lithium carbonate production process due to the use of different resources are divided into two categories: ore extraction of lithium and Salt Lake brine extraction. The main raw material for the production of lithium carbonate in foreign companies is Salt Lake Brine. In recent years, although China is actively developing salt Lake lithium resources,However, the development progress is slow because of the restriction of resource condition and technology.　　At present, the use of Salt Lake brine lithium technology is mainly in Qinghai Citic Guoan Technology Development Co., Ltd. and Tibet Shigatse Zabuye Lithium Industry Co., Ltd. At present, the main raw materials for producing lithium carbonate in China are mainly solid ores.　　and Tian Qi Lithium industry is the method of extracting lithium ore.　　But the industry experts are puzzled by the reference to the "only one in the world that uses the technology of lithium-ion to produce battery-grade lithium carbonate," as proposed by Tian Qi Li. Tangyugen, a professor at the School of Chemical Engineering at Zhongnan University, told reporters that he had not heard of such references in the industry before, "What is integration?" One-Step? As long as a process one link directly from the ore one-step to battery grade lithium carbonate? I haven't heard of this technique.　　"Even the industry experts are unheard of, that day Qi Li industry," the integration of lithium-ion production battery-grade lithium carbonate technology, what is the technology?　　The reporter thumbed through the prospectus and found that the company did not make a corresponding statement in the prospectus, which was interpreted as "directly extracting battery-grade lithium carbonate from the ore". The traditional ore-extracting lithium is extracted from lithium pyroxene to industrial grade lithium carbonate and then purified into battery-grade lithium carbonate products.　　is lithium pyroxene directly extracted from battery grade lithium carbonate, does that mean that the lithium-ion industry has skipped the industrial grade of lithium carbonate? Pan-Asian Lithium industry general manager to Li Nanping said: "Now the domestic lithium industry is mostly using ore to extract lithium, the process is more complex, there are many processes, if the Tian Qi lithium industry has a link and others are different is possible, but if this whole process is unique to him, it is impossible, the ore extraction technology in the industry is not a secret. "If so, what could this link be?" Is it unique to Tian Qi lithium industry?　　How valuable is it?　　The reporter learned that at present the industrial grade lithium carbonate further purification for battery-grade lithium carbonate products are the main means of caustic method, electrolysis, hydrogen and oxygen decomposition method, recrystallization method.　　Professor Lou Taiping, Northeastern University, said that, as far as he knew, the lithium industry was not directly extracted from the ore into battery-grade lithium carbonate and lithium chloride, which must also undergo an industrial-grade lithium carbonate link. He told reporters, "Tian Qi Lithium industry's technical advantage is that in the final purification link, there is a process to produce a high purity of lithium carbonate."　　"But he says this is actually just a matter of purity, not a very core technical advantage." Lithium chloride technology for Tian Qi lithium industry. He said that the technology of the Tian Qi lithium industry is mainly "an ion exchange sodium removal technology, can reduce the sodium content." Because the general lithium chloride is extracted from the ore with sodium salts, it is easy to mix sodium and lithium in the product, but the sodium lithium is difficult to separate, and the lithium ion exchange sodium removal technology is easier to remove sodium. "Lou Taiping said that the technology of extracting lithium chloride from ores is really important, but the technology of ion exchange and sodium removal is not unique to the lithium industry." The technology, he says, was previously a project at Northeastern University, whichTo sell to the tin Qi industry, but also sold to the Xinjiang lithium Salt Factory, but also now a part of private enterprises are also used.　　As for whether there are other technologies that may be unique to lithium-ion battery-grade lithium carbonate, Lou Taiping and Tangyugen all said that although it is not clear the specific circumstances, but its propaganda "the world's only use of ore lithium carbonate production of lithium-ion manufacturers", obviously exaggerated. As of the deadline, the reporter was not able to get a response from the Tian Qi lithium industry.
