Abstract

Rechargeable lithium-air battery is studied using Pd/mesoporous α-MnO₂ air composite electrode. In the present work, we have studied the preparation and electrochemical performance of ordered mesoporous α-MnO₂ as a cathode catalyst for rechargeable Li-air batteries. α-MnO₂ was prepared by reduction of KMnO₄ solution in acidic aqueous solution followed by successive proton and alkali-ion exchange method. α-MnO₂ with high surface area of 33-133.0 m ² g^-1 was successively synthesized and used as an electrode catalyst for Li-air battery. It was found that the mixture of Pd and mesoporous α-MnO₂ electrode shows the high activity to oxidation and reduction of Li to form Li₂O₂ or Li ₂O. Application of Pd/mesoporous α-MnO₂, which is mixed with teflonized acetylene binder (TAB), for air electrode is effective for decreasing the charge potential and also improved the energy efficiency as well as cyclability.
