| dc.description.abstract | 本實驗將使用噴霧造粒法(spray granulation)進行中熵氧化物粉體之製備，並進一步作為鋰離子電池之負極材料進行研究。此製程技術常使用於合成陶瓷粉末，該技術具有粒徑均勻等優點，能有利於電極材料之應用。
本研究主要探討中熵氧化物用於鋰離子電池負極並透過熵穩定特性對電化學性能表現之影響，包含電池容量與循環穩定性等方面。在鋰離子電池實作成果方面，本研究開發之高熵氧化物負極材料，經鋰離子半電池之測試，在50mAh g-1之電流下，其庫倫效率達到了 98% 以上之穩定表現，進一步證實了熵穩定作用大幅提高了循環穩定性，證明高熵氧化物未來將具備替代現今鋰離子電池電極材料之潛力。 | zh_TW |
| dc.description.abstract | In this study, spray granulation will be used to prepare medium entropy oxide powder, and will be further studied as an anode material for lithium-ion batteries. Spray granulation is often used to synthesize powders. This fabrication process not only has the advantages of uniform particle size, but also suitable for the application of electrode materials. This study uses the medium entropy oxide powder prepared by the spray granulation method for the application of lithium-ion battery anode materials, and discuss the electrochemical performance of medium entropy oxides.
In terms of the results of the performance of lithium-ion batteries, the medium entropy oxide anode material developed in this research has been tested by a lithium-ion half-cell. In addition, it can be further confirmed that entropy stability greatly improves cycle stability, which proved that the high entropy oxide will have the potential to replace current lithium-ion battery electrode materials in the future. | en_US |
