DESCRIPTION:I will discuss energy storage systems incorporating graphene\,
  such as silicon-graphene hybrids\, with an introduction to solvothermally
  synthesized transition metal dichalcogenides. Silicon-graphene (Si-FLG) c
 omposite electrode have been optimised and fabricated using a pilot-scale 
 manufacturing method. A comprehensive study on the electrochemical perform
 ance and the impedance response using electrochemical impedance spectrosco
 py (EIS) is discussed. The study demonstrated that the incorporation of FL
 G results in significant performance improvement in terms of cyclability\,
  capacity retention\, electronic conductivity\, diffusion properties and t
 ensile parameters. Moreover\, the diffusion impedance during Si phase chan
 ge as well as the variation against cycle number was investigated through 
 Staircase Potentio-Electrochemical Impedance Spectroscopy (SPEIS)\, which 
 is more comprehensive and straightforward than previous state-of-charge (S
 oC) based diffusion study. I will also discuss anode chemistry development
  based around MoS2. graphene hybrids for Li and Na-ion energy storage.\n
