CCTV's "Focus Interview" focuses on Henan enterprises polyfluoro: global lithium battery industry stealth champion

Henan Daily Client reporter Yao Guangqiang correspondent Zhao Galing

On the evening of August 19th, CCTV's "Focus Interview" aired "The Invisible Champions Pursuing Me in the Extreme" Lithium ", focusing on the two stealth champion companies in the lithium battery industry, one of which is the polyfluoro multi -new material shares from our province Limited, it tells the hardships and achievements of the "stuck neck" technology in succession.

The show was reported like this--

The new energy vehicle industry is a new industry supported by my country, and lithium batteries are the key components of new energy vehicles. In recent years, the rapid growth of the new energy vehicle industry in my country has a lot to do with my country's manufacturing capabilities on lithium batteries. The manufacture of lithium batteries requires four key materials: positive electrode, negative electrode, electrolyte, and diaphragm. Now these four major materials have all been localized, which has flattened the development of the entire lithium battery industry in my country. Among them, the upstream and downstream industrial chain collaboration is inseparable, and the role of the invisible champion Popular Fluoromy is inseparable.

The show said that electrolyte is an important part of a lithium ion battery. The blood of the lithium battery is critical to the performance of the battery. Lithium hexifluoropathic acid is the most important core component in the electrolyte. About 50%of the cost of electrolyte. In 2021, the total output of lithium global hexofluorophosphate was 68,000 tons, of which nearly one -third of them came from polyfluoropoly new materials Co., Ltd. Since 2014, the production and sales of lithium hexafluorophosphate for 8 consecutive years have ranked first in the world.

"First, I am the largest status and the scale of production and sales; second, our iterative technology is the strongest; third, we understand the future development. Now we have started formulating the international standards for lithium hexafluorophone." Speaking of today, we are talking about today In terms of corporate status, Li Shijiang, chairman of Duofluoro, is full of anger. And more than ten years ago, he dared not think of it. At that time, the core raw materials of China's lithium battery electrolytes, and lithium hexafluorophosphate rely on imports.

In 2006, Li Shijiang went to a foreign company to produce lithium hexifluoro. Li Shijiang told that inspection experience: "It's good to talk about it, just don't let the production line. Saying lithium hexarin is the result of long -term technology accumulation. You really can't do this."

Lithium hexal fluoropensive is the "Pearl in the Crown" in the field of fluoride, which sells for more than 1 million yuan per ton. It is difficult for enterprises to bear by buying a huge cost from abroad.

As a result, Li Shijiang was determined to develop lithium hexofluorophosphate. At that time, the company did not even have the most basic equipment required for experiments. They could only start from scratch according to the existing chemical principles.

Yan Chunsheng Yan Chunsheng said: "It is a raw material of high toxic, high risk, and high corrosion. There is no cooling device in summer. Hydrogen fluoride is very easy to gasify, especially water -free hydrogen fluoride. No one knows how to take it from the production line. In the experimental bottle, I opened it for the first time, but I trembled, and I was scared. "

In the process of technological tackling, the R & D team has encountered several explosions. Although it has not caused casualties, it also allows everyone to tremble every step, such as thin ice.

After two years of hard work, in 2008, polyflorism finally developed lithium hexfluorophosphate. Although only 2 grams, the enterprise entertains up and down. After continuous research iterative iteration, in 2011, the output of polyfluorofluorophone lithium phosphate reached 1,000 tons, becoming the first domestic self -developed and industrialized lithium hexafluorophosphate supplier.

Because of the technical breakthroughs and support for the national new energy industry, more than the second prize of the National Science and Technology Progress of Science and Technology than in 2017, and trained a number of skill -type talents. They continue to summarize their experiences in practice and improve production standards.

Feng Xiaogang is the director of a multi -fluoride branch. The factory mainly produces electronic -grade hydrofluoric acid. This is a high -purity electronic chemical. It is a key material for etching and cleaning semiconductor chips. The requirements are extremely high, so each operation of the production process and the purity of the production environment have the most stringent standards, and even the working status of employees must be kept stable.

Skills talents in various links are condensed together to create first -class products together. To continuously improve and be invincible in global competition, we must not only cultivate and rely on internal talents, but also use the "brain" of external wisdom.

On August 6 this year, Li Shijiang led a multi -fluoride executive team to communicate with the professors of the Department of Chemical Engineering of Tsinghua University. The two -day meeting mainly focused on key technical research and industrial development planning. With the help of "external brain" to practice internal skills and strengthening industry -university -research cooperation, Dorflo has not been interrupted over the years.

Not long ago, polyfluoro announced that the PPT -grade electronic hydrofluoric acid they produced in the United States and South Korea officially entered TSMC's qualified supplier system after entering the United States and South Korea. This means that their products have been recognized by the strongest player in the world semiconductor industry.

To produce PPT -level electronic -grade hydrofluoric acid, it is necessary to reach one -trillionth of cleanliness. This is the world's highest level for semiconductor electronic hydrofluoric acid. Multiofluoro is to overcome this "card neck" technology. 12 years.

Li Shijiang said that the technique of overcome the "card neck" has enhanced our nation's self -confidence. Individuals can't do groups, groups can't do the platform, the platform can't do the trend ... we have caught up with the good era.
