Abstract

High-resolution transmission electron microscopy (HRTEM) study of heavily fluorinated carbon nanofibers was performed under an ultra high voltage transmission electron microscope (UHVTEM). TEM observation showed rapid transformation of the disordered structure of fluorinated nanofiber to the cylindrical layer structure that is same as the non-fluorinated nanofiber. This observation suggests that electron beam irradiation helps fluorine atoms to dissociate from the carbon atoms. Li-ion secondary battery test cell using fluorinated nanofibers was prepared and the battery performance was tested as a function of cycling.
