ABSTRACT WITHDRAWN

We propose a low cost and simple method to prepare carbon hybrid structure-based electrodes in this study. Hybrid-structure Carbon Nanostrures were obtained using a zeolite as a template. The resulting carbon nanostructures are mostly configured by Graphene and multiwall carbon nanotubes (G/MWCNTs). The G/MWCNTs were dispersed onto the shallow surface of alumina foil forming as the electrodes. The electrical conductivity and dispersed morphology of the G/MWCNTs -based conductive electrode were examined by atomic force microscope (AFM), scanning electron microscope (SEM) and transmission electron microscope (TEM). Using the standard method we assembled the Lithium Ion Battery in the Ar-filled glove box, we used LiPF6 with EC:DMC::1:2 ratio as the electrolyte, lithium foil as the counter electrode and G/MWCNTs material. The specific capacity and cycle-life stability of the G/MWCNTs-based lithium ion battery was investigated by cyclic voltammetry analysis.
