Public Announcement on the Technical Transformation Project of Lithium Hexafluorophosphate at Shilei Fluorine Materials in Jiangxi 2025-10-24 15:14:14 Recently, information regarding the technical transformation project of lithium hexafluorophosphate at Shilei Fluorine Materials’ Huichang facility was posted for approval on relevant websites. Basic Information on the Project: Project Name: Shilei Fluorine Materials’ Huichang Lithium Hexafluorophosphate Technology Upgrade Project. Location of Construction: Jiangxi Huichang Fluorine Chemical Industry Base. Constructor: Jiangxi Shilei Fluorine Materials Co., Ltd. Project Investment: The total investment in this project is 30 million yuan, of which approximately 300,000 yuan is allocated to environmental protection measures, accounting for 1% of the total investment. Overview of the Construction Project: The total area occupied by the project’s factory complex is 30,218 square meters; no additional land will be used for this project. The project makes use of the existing production line with an annual output of 9,000 tons of lithium hexafluorophosphate, warehouses, and various supporting facilities; the total construction area is 28,437.48㎡, with no new buildings being constructed. However, equipment upgrades require the reinforcement of the building foundation. By utilizing the existing equipment in the synthesis section, 8 gas generation units, 2 mother liquor units, 2 clear liquid units, 4 modulation units, 4 synthesis units, and 4 drying units from that section will be retained, with no additional equipment or facilities added to the synthesis section ； The refining section has been equipped with 1 additional crushing unit, 1 blower, 1 classifier, 1 dust collector, 2 converters, 4 lithium salt storage tanks, 1 solid-liquid separator, 1 pneumatic conveying system, and 1 intelligent control system ； More than 10 various types of material transfer pumps, etc. Process after technical modification: Phosphorus pentachloride reacts with anhydrous hydrogen fluoride to produce phosphorus pentafluoride gas, which is filtered by a gas filtration system before entering the synthesis tank. Lithium fluoride, after being prepared, enters the synthesis tank from a preparation tank; there, phosphorus pentafluoride reacts with lithium fluoride to yield lithium hexafluorophosphate, and crystals precipitate in a dynamic process. These lithium hexafluorophosphate crystals are dried using drying equipment to produce semi-finished products, which are then crushed and further dried to become the final products ready for shipment. This project involves technical upgrades to the existing 9,000-ton lithium hexafluorophosphate production facility, while the existing 6,000-ton lithium hexafluorophosphate plant remains unchanged. After the technical upgrades, the products and production capacity of this project are 18,000 tons per year of lithium hexafluorophosphate, along with 25,200 tons per year of hydrofluoric acid as a by-product, and 108,000 tons per year of hydrochloric acid. Upon completion and commissioning of this project, the plant’s total production capacity will be 24,000 tons per year of lithium hexafluorophosphate, with 33,600 tons per year of hydrofluoric acid and 1,440,000 tons per year of hydrochloric acid as by-products. Jiangxi Shilei Fluorine Materials Co., Ltd. was established in June 2013; it is a wholly-owned subsidiary of Jiangxi Shilei Group Co., Ltd., with its headquarters located in the Fluoride Chemical Industry Base in Huichang County, Ganzhou City, Jiangxi Province. As a **high-tech enterprise, the company focuses on the research and development as well as production of fluorine-containing new materials and lithium battery materials, having established a complete industrial chain that spans from fluorspar resources to lithium battery materials. Its core products include lithium hexafluorophosphate, lithium-ion battery electrolytes, and hydrofluoric acid.
