Romanechite-structured Na(0.31)MnO(1.9) nanofibers as high-performance cathode material for a sodium-ion battery.
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.
