Group 1 - The article discusses the environmental impact assessment draft for the technical transformation project of Sichuan Yingda Lithium Battery New Materials Co., Ltd., which aims to produce 100,000 tons/year of lithium-ion battery cathode material lithium iron phosphate precursor [1] - The project involves an investment of 30 million yuan for optimizing the industrial route and capacity integration, adjusting the existing production capacity from 40,000 tons of sodium-based lithium iron phosphate and 60,000 tons of ammonium-based lithium iron phosphate to 100,000 tons of ammonium-based lithium iron phosphate [1] - The construction will be carried out in three phases, with the first phase involving a production line with a capacity of 25,000 tons/year, the second phase adding two more production lines for a total of 50,000 tons/year, and the third phase adding another production line for an additional 25,000 tons/year [1] Group 2 - The project will enhance the self-sufficiency of raw material supply by replacing externally sourced monoammonium phosphate with a reaction process using ammonia water and dilute phosphoric acid [1] - Energy-saving upgrades will be implemented in the drying section, along with the addition of a waste gas treatment system and other environmental protection facilities [1] - Upon completion, the project will achieve an annual production capacity of 100,000 tons of lithium-ion battery cathode material lithium iron phosphate precursor, relying on existing project facilities [1]
