| 摘要: 通过引入抗氧化剂（抗坏血酸）和配位剂（柠檬酸钠），采用共沉淀法在室温下制备出了高钠含量、低缺陷的铁基普鲁士蓝材料。由于高的钠含量和低的晶体缺陷，该材料在0.1C时容量可达110.0 mAh·g-1。除了普鲁士蓝材料独特的开放框架结构，其多边界结构和低的缺陷，使该材料表现出优异的倍率性能和循环稳定性。在10C大电流下，容量仍有86.6 mAh·g-1，1C电流下经过1 300次循环，容量保持在90.1 mAh·g-1，容量保持率达到86.9%。 | |

| Abstract: In this work, Na-rich, low-defect Fe-based Prussian blue material has been synthesized by coprecipitation method at room temperature using antioxidant (ascorbic acid) and chelating agent (sodium citrate). At 0.1C, the material exhibited a high capacity of 110.0 mAh·g-1 due to high Na content and low crystal defect. The material also showed excellent rate capability and cycling stability due to the border-rich structure and low defect, besides unique open framework structure of the Prussian blue material. At a current rate up to 10C, the material can still yield a capacity of 86.6 mAh·g-1. After 1 300 cycles at current density of 1C, the material could keep a capacity of 90.1 mAh·g-1, corresponding to the capacity retention of 86.9%. | |
