リチウム空気電池放電特性に及ぼす正極構造と濡れ性の影響

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, we focused on the effects of the porous cathode structure and wettability of the electrolyte on discharge performance, and attempted to increase the effective reaction area in the electrode and reduce oxygen transport resistance. As a result, it was observed that the discharge performance significantly varies depending on the formation of the electrolyte thin film and the partial infiltration of the electrolyte into the porous electrode.
