首次开发了一种由钠镁矾结构的Na（0.31）MnO（1.9）纳米纤维组成的新型钠离子电池正极材料。它可以提供>100 mA h g（-1）的Na吸收容量，具有上级高倍率能力和在2-4.5 V vs. Na（+）/Na的电压范围内的良好循环性能，并且表现出在正常放电倍率下快速充电的独特能力。
A new cathode material composed of romanechite-structured Na(0.31)MnO(1.9) nanofibers is developed for sodium-ion batteries for the first time. It can deliver a Na-uptake capacity of >100 mA h g(-1) with a superior high-rate capability and good cycling performance in the voltage range of 2-4.5 V vs. Na(+)/Na, and exhibit the unique ability of fast charging with the normal discharge rate.
