Silicon/MWCNT composite electrodes were produced using high-speed planetary ball milling. Content of MWCNT were altered in silicon/MWCNT composite electrodes and effect of MWCNT content on the electrochemical performance of silicon electrodes were characterized by scanning electron microscopy and X-ray diffraction techniques. Coin type CR2016 test cells were assembled by using produced nanocomposite electrodes. Prepared test cells were electrochemically cycled at a current density of 200 mA/g. Furthermore, cyclic voltammetry curve of composite electrodes were performed to investigate electrochemical reactions between electrode and electrolyte.
