Abstract© 2018 Elsevier Ltd MnF2 infiltrated-CNT fabrics was prepared by surfactant-aided impregnation of MnSiF6 precursors in acid-treated CNT fabric followed by annealing MnSiF6-loaded CNT fabric. The structural and morphological characterizations by X-ray diffraction, scanning electron microscopy (SEM), and transmission electron microscopy (TEM) confirmed the formation of MnF2 nanoparticles (average size: 20–30 nm) within CNT fabric structure. Galvanostatic charge-discharge tests of CNT-MnF2 nanocomposite fabrics showed excellent electrochemical performance and good cycle stability between 0.4 and 4.0 V vs Li/Li+. A specific capacity of 388 mAh/g was measured at 0.1C for CNT-MnF2 fabric with 70% MnF2 loading after 100 cycles. Stable cyclability and good rate performance were obtained at high charge-discharge cycling rates. MnF2 loading largely affect the performance of MnF2 infiltrated-CNT fabrics cathodes when lower than 70% MnF2 loaded-CNT fabrics were prepared. It can be concluded that nano-sized active materials infiltrated inside conductive carbon matrix in optimized content can lead to rapid kinetics and stable performance for flexible metal fluoride-based cathode materials.
