Abstract:Now facing the global resources and energy crisis,the development of mineral resources and the synthesis of new energy materials become a hot research field. In this paper, the relatively in-depth research was done about the extraction and purification of phosphorus from low-grade phosphate ores as a source of phosphorus, and the preparation of LiFePO4using the obtained phosphorus was also investigated.The technology of synthesizing LiFePO4from low-grade phosphate ores was proposed. The work is des...
