On the 31st of the month, the Management Committee of Bijie High-Tech Zone in Guizhou Province issued the “First Public Announcement on the Environmental Impact Assessment for the Pyrochemical Lithium Iron Phosphate Production Project in Bijie High-Tech Zone”. According to the public information, the developer of this project is Bijie Rongbai Lithium Battery Materials Co., Ltd. The project involves adapting the existing buildings and facilities in the former Lifan factory site, while also constructing the necessary utility systems and auxiliary facilities; the overall plan is to build a pyrometallurgical production line with an annual output of 1 million tons of lithium iron phosphate. The project is implemented in three phases: Phase 1 will achieve an annual production capacity of 300,000 tons; Phase 2 will add another 400,000 tons per year to the production capacity; and Phase 3 will add another 300,000 tons per year (the scope of this evaluation covers only Phase 1). In terms of the process, the yellow material is sintered at high temperature under nitrogen protection to produce lithium iron phosphate (LiFePO4), with water and carbon dioxide as by-products. The resulting lithium iron phosphate cathode material is then crushed, deironed, packaged, and stored. Complementary public auxiliary systems such as power supply and distribution, circulating water, nitrogen production, and gas pressure regulation are installed.
