Abstract

In situ high energy X-ray diffraction (HEXRD) and in situ X-ray absorption near edge spectroscopy (XANES) were carried out to understand the solid state synthesis of Na_xMnO₂, with particular interest on the synthesis of P2 type Na_2/3MnO₂. It was found that there were multi intermediate phases formed before NaMnO₂ appeared at about 600 °C. And the final product after cooling process is a combination of O'3 NaMnO₂ with P2 Na_2/3MnO₂. A P2 type Na_2/3MnO₂ was synthesized at reduced temperature (600 °C). The influence of Na₂CO₃ impurity on the electrochemical performance of P2 Na_2/3MnO₂ was thoroughly investigated in our work. It was found that the content of Na₂CO₃ can be reduced by optimizing Na₂CO₃/MnCO₃ ratio during the solid state reaction or other post treatment such as washing with water. We expected our results could provide a good guide for future development of high performance cathode materials for sodium-ion batteries.
