Abstract: A flexible paper was composited by active material of fluorinated graphite (CF1), multiwalled carbon nanotubes (MWCNTs) and cellulose fibers. After carbonization, the paper was used as cathode to assemble Li/CFx primary batteries. The structures and properties were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermal gravimetric analyzer (TGA), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The electrochemical performance was tested by galvanostatic discharge and electrochemical impedance spectroscopy (EIS). At the same discharge rate, CF1-MWCNTs-Cel paper as cathode exhibited higher discharge capacity and discharge plateau than those of CF1-Al electrode as cathode. CF1-MWCNTs-Cel paper and CF1-Al electrodes respectively reached 440.4 mAh/g and 321 mAh/g at 2C, CF1-MWCNTs-Cel paper exhibited a 37% higher capacity than that of CF1-Al electrodes. CF1-MWCNTs-Cel paper as cathode shows excellent electrochemical performance.
