Sodium manganese oxide cathode synthesized using self-ion exchange for Li+/Na+ Hybrid Ion Battery |
| 초록 |
A simple self-ion exchange method can be used to synthesize P2-structured manganese sodium oxide. The low-cost electrode of the lithium/sodium hybrid ion battery after the ion exchange process provides new data on the direct use of sodium manganese oxide instead of lithium analogs. According to the analysis by X-ray diffraction analysis,, during the cell stabilization process, sodium manganese oxide undergoes ion exchange through the electrolyte. Its own ion exchange material has a high discharge capacity of 195 mAh g-1 and can run stably for 50 cycles at 3.0 V. In situ X-ray diffraction and ectopic X-ray absorption near the edge structure confirmed the reversible redox reaction and stable structural changes. Ex-situ inductively coupled plasma atomic emission spectrometry confirmed that residual sodium ions act as pillars during structural cycling. |
