Abstract
The oxidation of a carbon binder that occurred during a charge in a carbon– air electrode for a Li-air battery resulted in an excessively high charge potential of 4.2 V. The air electrode activity for the Li-air battery was studied on various metals or metal oxides and the mixture of Pd and shows the high activity to oxidation and reduction of Li to form or , respectively. Although the discharge capacity decreased, the application of without a carbon binder for the air electrode is effective to decrease the charge potential and to improve the energy efficiency from 60 to 89%.Keywords
