Abstract

The invention relates to an innovative process for synthesizing battery-grade FePO₄ from raw phosphate rock without prior purification. By precisely controlling the pH and redox potential of the solution, selective precipitation of FePO₄ is achieved with high purity, while impurities remain in solution. This simplified process eliminates the re-precipitation steps of conventional methods, thereby reducing production costs and time.
