Synthesis of TiO2/graphene nanocomposites to enhance the energy storage and stability of sodium ion batteries:

  • Synthesis of few-layer of graphene in a microwave plasma
  • Synthesis of ultrafine anatase TiO2 by spray-flame synthesis
  • Formation of TiO2-graphene nanocomposites using the wetphase strategy
  • Investigate the performance of sodium-ion battery with a TiO2-graphene nanocomposite anode
