Synthesis of silicon and carbon nanocomposites

Synthesis of silicon and carbon nanocomposites

Reduced graphene oxide and silicon (rGO@Si) nanoflakes and carbon-coated silicon (Si@C) particles are prepared by reducing pre-synthesised GO@SiO2 and SiO2@C with magnesium powder at 650°C. These silicon and carbon nanocomposites of different sizes and thickness are tested as anodes for Li ion batte...
