• 一般注記: Na2/3Fe1/3Mn2/3O2 cathode active materials were prepared by spray pyrolysis. As-prepared powders had spherical morphology with dense microstructure which had an average diameter of about 1μm with broad size distribution. The particle morphology of Na2/3Fe1/3Mn2/3O2 cathode active materials were influenced by the calcination and the polygonal morphology was obtained at 900℃. XRD showed that as-prepared powders was well crystallized to P2 type structure after the calcination at 800℃. The electrochemical measurement of Na2/3Fe1/3Mn2/3O2 cathode showed that the two plateaus were observed at 3V and 4.3V in rechargeable curve and the discharge capacity of Na2/3Fe1/3Mn2/3O2 cathode was 203mAh/g at O.O1C. After 1OOth cycle, the discharge capacity and capacity retention of Na2/3Fe1/3Mn2/3O2 cathode was 116mAh/g and 70% at O.1C, respectively.
