Abstract

In this study, of α-MnO₂/Graphene/CNT nanocomposites were
produced and characterized as electrode for Li-O₂ batteries. Graphene
was produced with Hummer method and carbon nano tubes were added to graphene as
spacers between layers. α-MnO₂nanorods were synthesized and α-MnO₂/Graphene/CNT
nanocomposites were fabricated by vacuum filtration technique as a paper
electrode. α-MnO₂nanorods were added to composite at three different rates and electrodes
were characterized by FESEM and XRD. The electrochemical characterization was
carried out in ECC-air test cells.  

Keywords
