By hmimcu Recently, CCTV’s “Focus Interview” column broadcasted an in-depth report on “Invisible Champions Pursue the Ultimate ‘Lithium’ with Me”, which described Dofluoroduo’s over ten years of overcoming the “stuck neck” technology, realizing the transition from following to running to The leading story shows the innovation and persistence of Chinese enterprises to break through overseas monopoly and become the world’s leading enterprises.
Innovation requires courage
. Around 2006, new energy vehicles first appeared in China. As a high-tech enterprise engaged in the research and development of inorganic fluorides, electronic chemicals, lithium batteries and related materials, DFD has taken a fancy to a key material in the supply chain of new energy vehicles: lithium hexafluorophosphate. Lithium hexafluorophosphate is the core material of lithium-ion battery electrolyte with high technical content, accounting for about 50% of the electrolyte cost. In 2006, the core technology of lithium hexafluorophosphate was completely monopolized by foreign countries. Li Shijiang, the chairman of Polyfluoride, once visited a foreign company that produced lithium hexafluorophosphate. After the inspection, Li Shijiang recalled: “It was a good talk, but the production line was not allowed to be seen.”
The breakthrough and innovation of Polyfluoride is in such a domestic technological gap , developed under the background of foreign technology blockade. At that time, enterprises did not even have the most basic equipment needed for experiments. They could only start from scratch according to the principles of chemical engineering, and practice while exploring. Recalling the innovation process of lithium hexafluorophosphate, Yan Chunsheng, chief engineer of polyfluoride, has a lot of feelings: “They are all raw materials with high toxicity, high risk and high corrosion. There is no cooling device in summer, and hydrogen fluoride is very easy to gasify, especially anhydrous hydrogen fluoride. , no one knows how to take it from the production line to the experimental vial. The first time I opened it, but my hands were shaking, and I was also afraid.” In order to achieve technical breakthroughs, the R&D team also encountered several explosions.
After more than two years of hard work on the robot automatic packaging production line of high-purity crystalline lithium hexafluorophosphate
, in 2008, polyfluoride finally independently developed crystalline lithium hexafluorophosphate. Although it is only 2 grams, it makes the company rejoice. After continuous research and iteration, in 2011, the output of polyfluoride lithium hexafluorophosphate reached 1,000 tons, becoming the first domestic independent research and development and industrialization of crystalline lithium hexafluorophosphate supplier.
Persistence can achieve
long-term development. In the course of more than 30 years of enterprise development, DFD has shown the tenacious spirit of “grinding an iron pestle into a needle”. Based on talents and based on customer trust, it took more than ten years to forge the “two carriages” that drive the development of the enterprise.
Being in a fourth-tier city, DFD does not have the inherent advantage of attracting talents. In order to build a talent team capable of tackling fortifications and daring to make breakthroughs, Fluoride has proposed a win-win training model with talents. Dofluoroduo has signed technical cooperation contracts with 7 research institutes of the Chinese Academy of Sciences, signed a postgraduate training contract with Tsinghua University, and signed a technology development contract such as “micro-channel reaction” and “micro-reaction”; jointly established Wisdom Element with Zhengzhou University The research institute puts the key elements frequently studied by polyfluoride – “fluorine, lithium, silicon” and the interaction of related elements on the digital platform for more in-depth research; jointly established the new material industry college with Henan University of Technology , into an organic system, the introduction of talents in batches. The cooperation between production and research has attracted more talents from colleges and universities for enterprises, and has won many forces for technological breakthroughs. The school also enjoys a lot of benefits from it. The professor-level senior engineers of Polyfluoride can go to the university to give lectures, and the professors and lecturers of the university can also work as engineers at Polyfluoride.

Gaining the trust of customers is another hurdle encountered in the development of Fluorocarbon. Electronic grade hydrofluoric acid, as the main product of polyfluoride, although the product quality is reliable, reaching the world’s highest level of electronic grade hydrofluoric acid for semiconductors, but in the early stage of market expansion, when overseas big manufacturers occupy the main market share, domestic Customers worry that changing products will cause immeasurable losses to themselves, and the “cost of trust” is very high. For the products of polyfluoride, the customer has conducted repeated inspections and tests. In order to develop first-class corporate customers, Dofluoroduo has continuously communicated with experts, made tricks with experts, made rectifications according to customer requirements, and finally passed the quality certification of TSMC, the leading global semiconductor foundry company. In May this year, Dofluoroduo announced its The PPT grade (one-trillionth cleanliness) ultra-clean and high-purity electronic grade hydrofluoric acid produced has officially entered the TSMC qualified supplier system. display tft module
The outstanding achievements of heroic
enterprises in the times require not only the spirit of diligence, but also the courage to be the first. In 2006, the decision to do technical research on lithium hexafluorophosphate was a risky move. This technology requires many years of technical accumulation, and the investment return period is long. If it is unsuccessful, the company’s investment for many years will be lost. However, Dofuduo chose to be the “first to eat crab” enterprise. It is precisely because of this that DFD can seize the development opportunity when the production and sales volume of the new energy vehicle market has been rising year by year and the demand for lithium hexafluorophosphate has been rising. In 2021, the total global production of lithium hexafluorophosphate will reach 68,000 tons, of which nearly one-third will come from DFD New Materials Co., Ltd. Since 2014, the production and sales volume of polyfluoroduo has ranked first in the world for 8 consecutive years. On August 17, Dofluoroduo announced that the company’s main business revenue in the first half of the year increased by 106.78% year-on-year, and its net profit increased by 355.54% year-on-year.
In the face of the outstanding achievements made by the company, Li Shijiang was very indifferent. He said: “Individuals can’t do a group, a group can’t do a platform, and a platform can’t do the trend… We have caught up with the good times.” The ups and downs of the company are in Li Shijiang Seems to be normal. Under the circumstance that the market heat of the new energy vehicle industry chain is rising, DFD did not choose an artificially high price, but chose to establish contact with more customers at a reasonable price. At the same time, customers are invited to invest in polyfluoride, so as to establish property rights cooperation with the upstream and downstream of the industry, form a “community of destiny”, and improve the ability to resist market risks.
Facing the future, polyfluoroduo has always maintained an attitude of walking in the forefront of the times. Li Shijiang said: “We judge the frontier trends and development trends of the industry by looking at two road signs, one is a national-level project and the other is an international standard.” Over the years, DFD has undertaken 22 national-level projects. Through the development of one project after another, DFD leads the development of the industry and realizes the resonance of enterprise development and national strategy at the same frequency. At the same time, polyfluoride has continuously benchmarked against international standards, and has achieved a leap from participating in the formulation of international standards to presiding over the formulation of international standards. In 2018, more than 30 experts from 6 countries held a meeting in Polyfluoride to formulate international standards for fluoride salts. Polyfluoride is the convening unit of the international ISO/TC226 fluoride salt working group. This year, polyfluoride once again became the convening unit of the international ISO/TC 333 WG4 working group, and presided over the formulation of international standards for the analysis and detection methods of lithium hexafluorophosphate.
