| 英文摘要 | A series of iron-substituted layered P3-type manganese oxides, K0.45Mn1-xFexO2 (x=0, 0.1, 0.2, 0.3, 0.4 and 0.5) were fabricated using a convenient solid-state method and studied as cathode materials for potassium-ion batteries. The microstructure and morphology of the as-synthesized materials were examined by X-ray diffraction (XRD) and scanning electron microscope (SEM) techniques. The electrochemical characteristics of K0.45Mn1-xFexO2 samples have been investigated systematically and K0.45Mn0.8Fe0.2O2 shows the best cyclic stability and highest rate performance. It delivers a large reversible discharge capacity of 106.2 mAh g(-1) at 20 mA g(-1) with a capacity retention rate of 77.3% after 100 cycles. It also presents obviously enhanced rate performance with the capacity of 64.9 mAh g(-1) at 200 mA g(-1) and stable cycling capability of 44.7 mAh g(-1) after 100 cycles. The results demonstrate that the relatively small substitution (20%) at the transition metal site can improve the cycle stability during potassium ions insertion and extraction. Therefore, the layered P-3-K0.45Mn0.8Fe0.2O2 possibly serves as a potentially promising cathode material that made from completely earthabundant elements for potassium-ion batteries applications. |
