Industrial Preparation and Electrochemical Application of Iron Phosphate by Pure Iron Method
Lithium iron phosphate is widely used as a positive electrode material for lithium-ion batteries,and the precursor iron phosphate has also been rapidly developed recent years.The mainstream production process of iron phosphate,the ferrous sulfate method,has a long produc-tion process and a large amount of industrial wastewater treatment.This article proposes an industrial production method for preparing iron phos-phate using high-purity iron as raw material.This method is simple,and the process water can be recycled which makes low environmental pressure.In addition,we prepare lithium iron phosphate using the iron phosphate produced as the precursor,and test the electrochemical per-formance of it.The results show that the lithium iron phosphate prepared by the iron phosphate method had a sepecific capacity of≥160 mAh/g at a rate of 0.1C,fully meeting the application needs of the backend market.
