Abstract:
Herein, we developed a facile method for the synthesis of battery-grade ferric phosphate (FePO4·2H2O) using high-pressure hydrolyzed precipitates of cobalt-iron alloy acid solution. The size of the prepared FePO4·2H2O samples was about 5-10 μm, and the microstructure of FePO4·2H2O was polyhedral. The FePO4·2H2O samples exhibited a high Fe/P ratio (1.03) compared with standard ferric phosphate (0.98-1.02), indicating potentially good electrochemical performance. The significance of the current work is that we have developed an effective method for the resource utilization of solid waste containing iron.
