摘要：

Herein, we developed a facile method for the synthesis of battery-grade ferric phosphate (FePO4<middle dot>2H2O) using high-pressure hydrolyzed precipitates of cobalt-iron alloy acid solution. The size of the prepared FePO4<middle dot>2H2O samples was about 5-10 mu m, and the microstructure of FePO4<middle dot>2H2O was polyhedral. The FePO4<middle dot>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.
