This study demonstrates direct insitu-incorporation of metal oxides on carbon during synthesis and the associated application to nonaqueous Li-O2 battery catalysts. The partially oxidized Mn3O4 (Mn3O4/Mn5O8)-incorporated carbon cathode shows an average overpotential reduction of ~ 8% charge/discharge during 40 cycles in a rechargeable nonaqueous Li-O2 cell. Here, we suggested the possibility that only a small amount of the oxide species ( |
