Production and Characterization of α-MnO2/Graphene/CNT Nanocomposite Electrodes for Li-O2 Batteries

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.

Li-O2 Piller için α-MnO2/Grafen/KNT Nanokompozit Elektrotlarının Üretimi ve Karakterizasyonu

Abstract

Bu çalışmada Li-O₂ pilleri için elektrot malzemesi α-MnO₂/Grafen/KNT nanokompozitleri üretilmiş ve karakterize edilmiştir. Grafen Hummer metodu ile üretilmiş ve tabakalar arası boşluk yapıcı olarak karbon nano tüp ilavesi yapılmıştır. α-MnO₂ nano çubuklar sentezlenerek α-MnO₂/Grafen/KNT nanokompozitleri vakum filtrasyon yöntemi ile kağıt halinde elektrot olarak üretilmiştir. Üç farklı oranda ilave edilen α-MnO₂ nano çubukları ile elektrotların yapısal karakterizasyonu FESEM, XRD kullanılarak ve elektrokimyasal karakterizasyonu da ECC-hava test hücreleri ile yapılmıştır.
