Recently, Shanxi Xiang'an Energy Technology Co., Ltd. published the environmental impact assessment draft for public comment for its annual production of 30,000 mt of sodium-ion battery materials project. The project is located in the Fuyang Industrial Park, Xiangyuan Economic and Technological Development Zone, Changzhi City, Shanxi Province. The main part of the project and associated utilities include the construction of two production lines for sodium-ion battery cathode materials and one production line for anode materials, along with supporting pure water preparation, air compression systems, nitrogen generation systems, dehumidification systems, and cooling water circulation systems. The processes adopted include: pretreatment (mixing + sand milling + iron removal + spray drying), sagger loading, vibration leveling, grid insertion + sintering, and final treatment (jet milling + batch mixing + sieving + packaging). Once operational, the project will produce 25,000 mt of sodium-ion battery cathode materials and 5,000 mt of anode materials annually. The total investment of the project is 534 million yuan, with an environmental protection investment of 3.64 million yuan, accounting for 0.68%.
