Magnesium–Graphene Composite Coated on SS Mesh as Cathode Material for Rechargeable Magnesium ion Battery
- 41 Downloads
Rechargeable magnesium battery with a magnesium anode and magnesium–graphene (Mg–G) composite coated on SS mesh as cathode and ionic liquid electrolyte was developed. Magnesium–graphene composite was prepared by using the semi-metallurgy method. The composite was analyzed by field emission scanning electron microscopy, Fourier transform infrared spectroscopy, Raman spectroscopy, and X-ray diffraction studies. The electrochemical performance of magnesium–graphene composite was analyzed by cyclic voltammetry, impedance spectroscopy, and charge–discharge studies. The cyclic voltammetry of Mg–G cell showed good reversibility, and impedance spectra revealed reduced resistance of the cell. The cell-specific capacity was 55 mAh g−1, and average discharge voltage was 1.15 V at 0.1 mA cm−2 constant current. The cell showed good cycle life (80 cycles) indicating stable discharge capacity and electrochemical behavior.
