          <datacite:description xml:lang="ja" descriptionType="Abstract">水溶液系リチウム空気電池は高い理論重量エネルギー密度を有する。この電池の正極は活物質である酸素分子と中性あるいは塩基性の水溶液電解質の組み合わせから構成される。大気中の二酸化炭素と水溶液との反応を防止するため、本研究では酢酸酸性水溶液を適用した。また、この酸性電解液に耐える固体電解質薄膜をテープキャスト法で作成した。本電池系の開回路電圧は約4Vを示した。また加圧下で電池を作動させることによって酢酸の揮発を抑制し電池は安定した充放電サイクル特性を示した。</datacite:description>
          <datacite:description xml:lang="en" descriptionType="Abstract">Lithium-air batteries with aqueous solution have a high theoretical gravimetric energy density. The cathode of this battery consists of a combination of oxygen molecules and a neutral or basic aqueous solution electrolyte. To prevent reactions between atmospheric carbon dioxide and aqueous solutions, acidic acetic acid solutions were applied in this study. Solid electrolyte thin films that can withstand this acidic electrolyte solution were prepared by the tape casting method. The open circuit voltage of this battery system was approximately 4 V. By operating the battery under pressure, it showed stable charge-discharge cycle characteristics because the acetic acid volatilization was suppressed.</datacite:description>
