On January 20, the enterprise investment project for the first phase of Jiangxi Fuli New Energy Materials Technology Co., Ltd.’s facility with an annual production capacity of 50,000 tons of lithium hexafluorophosphate for use in new energy applications was approved on the relevant website. The relevant details of the project are as follows: On January 20, the enterprise investment project for the first phase of Jiangxi Fuli New Energy Materials Technology Co., Ltd.’s facility with an annual production capacity of 50,000 tons of lithium hexafluorophosphate for use in new energy applications was approved on the relevant website. The details of the project are as follows: Project name: Phase I Project for the Annual Production of 50,000 Tons of Lithium Hexafluorophosphate for New Energy Applications ； Construction unit: Jiangxi Fuli New Energy Materials Technology Co., Ltd ； Total investment: 5.1 billion yuan, with the first-phase project costing 4.5 billion yuan ； Construction location: Leping Industrial Park, Jiangxi ； Construction content and scale: The main components of this project involve using yellow phosphorus and liquid chlorine as raw materials to produce phosphorus pentachloride through processes such as chlorination, phosphorus washing, and re-chlorination ； Using phosphorus pentachloride, hydrogen fluoride, and lithium fluoride as raw materials, lithium hexafluorophosphate is produced through processes such as fluorination, condensation, solvent removal, and crystallization. As a result, a production line capable of producing 20,000 tons per year of phosphorus pentachloride (1,390.39 tons per year for internal use and 18,609.61 tons per year for sale) and 1,000 tons per year of lithium hexafluorophosphate is established, with 390.44 tons per year of 30% hydrochloric acid as a by-product. Regarding Jiangxi Fuli New Energy Materials Technology Co., Ltd.: Established in 2022, the company’s registered address is on the south side of Industrial Road 19 in Leping Industrial Park, Leping City, Jingdezhen City, Jiangxi Province. It operates in the pharmaceutical manufacturing industry, and its business scope includes: research and development of biochemical products, research and development of new materials, production of chemical products (excluding those that require special permits), sales of chemical products (excluding those that require special permits), as well as technical services, development, consultation, exchange, transfer, and promotion of technologies. Related link: Jiangxi Fuli New Energy Materials Technology Co., Ltd.’s new energy project for the annual production of 50,000 tons of lithium hexafluorophosphate is being built in three phases; the first phase involves the construction of production lines for 1,000 tons of lithium hexafluorophosphate and 20,000 tons of phosphorus pentachloride ； Phase 2 construction of a 0.9-ton lithium hexafluorophosphate production line ； Phase 3 involves the construction of a production facility capable of producing 40,000 tons of lithium hexafluorophosphate, as well as the expansion of the phosphorus pentachloride production line to an output of 50,000 tons. The process consists of four steps: Step 1: Preparation of phosphorus trichloride, which is obtained by reacting yellow phosphorus with chlorine gas ； Step 2: Preparation of phosphorus pentachloride – Phosphorus trichloride obtained in Step 1 is reacted with chlorine to produce phosphorus pentachloride, or the phosphorus trichloride obtained in Step 1 is purified first before being reacted with chlorine to yield phosphorus pentachloride ； Step 3: Preparation of phosphorus pentafluoride – PCl5 is placed in a sealed reactor, and anhydrous HF is introduced to carry out the reaction and produce phosphorus pentafluoride. The gas mixture resulting from the reaction is passed through lithium fluoride for adsorption; after desorption, purified phosphorus pentafluoride gas is obtained ； The unadsorbed hydrogen chloride and hydrogen fluoride gases are then separated through adsorption under varying temperature and pressure, thereby yielding hydrogen chloride gas and hydrogen fluoride gas respectively ； Step 4: Preparation of lithium hexafluorophosphate – Liquid carbon dioxide or supercritical carbon dioxide fluid is used as a solvent, and phosphorus pentafluoride is reacted with lithium fluoride to produce lithium hexafluorophosphate.
