报道了一种新型层状正极材料Na-0.5[Ni0.23Fe0.13Mn0.63]O-2的合成、晶体结构和在钠电池中的电化学性能。X射线衍射研究和高分辨率扫描电子显微镜图像揭示了一个明确的P2型层状结构，而电化学测试表明，在高容量和循环寿命方面的优异特性。这种性能、低成本及其组分的环境相容性使Na-0.5[Ni0.23Fe0.13Mn0.63]O-2成为下一代钠离子电池最有前途的材料之一。
The synthesis of a new layered cathode material, Na-0.5[Ni0.23Fe0.13Mn0.63]O-2, and its characterization in terms of crystalline structure and electrochemical performance in a sodium cell is reported. X-ray diffraction studies and high resolution scanning electron microscopy images reveal a well-defined P2-type layered structure, while the electrochemical tests demonstrate excellent characteristics in terms of high capacity and cycle life. This performance, the low cost, and the environmental compatibility of its component poses Na-0.5[Ni0.23Fe0.13Mn0.63]O-2 to be among the most promising materials for the next generation of sodium-ion batteries.
