Description
リチウム空気電池は、以下の手順で作製した。
実施例10では、実施例7で高い性能を示したLiBH4+LiNH2を正極上で95℃で融解し、再凝固させることによって、正極/固体電解質の接触界面サイトを増加させることで電池性能の改善を試みた。
実施例11〜13では、実施例7で高い性能を示したLiBH4+LiNH2を空気極に混合することによって、正極/固体電解質の接触界面サイトを増加させることに電池性能の改善を試みた。
比較例として、有機電解液を用いた電池を作製した。実施例1〜10に記したセル構成で、固体電解質に代えて有機電解液である1mol/lLiPF6/炭酸プロピレン(PC)をセル内にセパレータとともに充填することにより電池を作製した。同一構成の電池を、5セル作製した。
