dc.description.abstract | Sodium-ion batteries offer a potential alternative or complementary system to lithium-ion batteries, which are widely used in many applications. For this purpose, layered O3-type NaCrO2 for use as a cathode material in sodium-ion batteries was synthesized via an emulsion-drying method. The produced NaCrO2 was modified using pitch as a carbon source and the products were tested in half and full cells using a NaPF6-based nonaqueous electrolyte solution. The carbon-coated NaCrO2 cathode material exhibits excellent capacity retention with superior rate capability up to a rate of 150 C (99 mA h (g oxide)(-1)), which corresponds to full discharge during 27 s. The surface conducting carbon layer plays a critically important role in the excellent performance of this cathode material. We confirmed the reaction process with sodium using X-ray diffraction and X-ray absorption spectroscopy. Thermal analysis using time-resolved X-ray diffraction also demonstrated the structural stability of carbon-coated Na0.5CrO2. Due to the excellent performance of the cathode material described herein, this study has the potential to promote the accelerated development of sodium-ion batteries for a large number of applications. | - |
