酸素輸送を向上させるリチウム空気電池正極構造の研究

抄録

Lithium-air battery attracts great attention because of its high energy density. However, due to the low solubility and diffusivity of oxygen in the electrolyte, oxygen transport to the reaction site of the positive electrode is limited. In this study, discharge experiments using glassy carbon were conducted to investigate the positive electrode structure effective for improving oxygen transport. The results showed that a smaller contact angle between the carbon and the electrolyte can improve the positive electrode performance. By optimizing the electrode structure and the electrolyte wettability, it is expected that oxygen transport (performance of the positive electrode) will be improved.
