On October 30, the groundbreaking ceremony for Duofu’s project to produce 20,000 tons of lithium hexafluorophosphate and related additives per year was held in the New Materials Industrial Park of Yangquan High-Tech Zone. It is reported that the total investment in this project is 1 billion yuan, with construction carried out in phases. The construction period for Phase 1 is 12 months, and it is planned to go into operation by the end of December 2022 ； The construction period for Phase 2 of the project is 12 months, with commissioning planned by the end of December 2024.
In July, Duofuduo announced its intention to build facilities for producing 100,000 tons of lithium hexafluorophosphate, 40,000 tons of lithium bis(fluorosulfonylimide) (LiFSI), and 10,000 tons of lithium difluorophosphate. The total investment amount is 5.15 billion yuan, with completion and full operation expected by the end of 2025. According to the information from Duofuduo’s research activity on October 19, the company’s annual production capacity for lithium hexafluorophosphate has now reached 15,000 tons, with shipments of around 13,000 tons expected by the end of 2021 ； By the end of 2022, an additional 40,000 tons of production capacity is planned to be added, bringing the total annual capacity to 55,000 tons; the annual production and sales volume is expected to exceed 30,000 tons ； Production and sales volumes after 2023 will increase gradually based on market conditions and expansion efforts.
From the production process of lithium hexafluorophosphate, the raw materials are phosphorus pentachloride, hydrofluoric acid, and lithium carbonate or lithium fluoride, with the production method being the HF solvent method. Since lithium hexafluorophosphate falls under the fluorine chemical industry, environmental approval processes are stringent, and the expansion cycle is expected to take 1 to 1.5 years. Moreover, hydrofluoric acid is highly corrosive; any shutdown during production can have a significant impact on equipment depreciation. Therefore, companies are reluctant to expand production in the absence of a clear customer connection.
Duofuduo currently stands out in the field of basic fluorine chemicals, while companies such as Dongyue and Sanyaifu focus on polymer fluorine materials.
