摘要

在此，我们开发了一种利用钴铁合金酸溶液的高压水解沉淀物合成电池级磷酸铁（FePO4-2H2O）的简便方法。制备的 FePO4-2H2O 样品的尺寸约为 5-10 μm，FePO4-2H2O 的显微结构为多面体。与标准磷酸铁（0.98-1.02）相比，FePO4-2H2O 样品显示出较高的 Fe/P 比（1.03），表明其具有潜在的良好电化学性能。当前工作的意义在于，我们开发出了一种有效的含铁固体废物资源化利用方法。

Synthesis of battery-grade FePO4·2H2O using high-pressure hydrolyzed precipitates of cobalt–iron alloy acid solution†

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.
