| dc.description.abstract | Layered cathode materials based on abundant, low cost raw materials have garnered interest in recent years. O3-type NaCrO2 is a promising cathode material as it offers decent energy density and is easy to synthesize. In this study, calcium doped NaCrO2 was synthesized using a solid-state method and the resulting [Na1-2xCax]CrO2 materials were studied in sodium cells. Compared to calcium-free NaCrO2, [Na0.9Ca0.05]CrO2 has improved capacity retention without sacrificing reversible capacity. The enhanced performance was ascribed to structural stabilization of NaCrO2 by Ca-doping, as observed by ex-situ X-ray diffraction. Finally, calcium doped NaCrO2 was also found to have improved air-stability than the pristine material. | en_US |
