Germanium (Ge) nanocrystals with and without multiwalled carbon nanotubes (MWCNTs) are synthesised in via solvothermal approach. The active anode material is characterized by X-ray Diffraction pattern (XRD), Transmission Electron Microscopy (TEM) and Raman spectroscopy. Cyclic voltammetry and galvanostatic charging and discharging are employed to characterize electrochemical behaviour. The results show Ge-MWCNTs nanocomposite improved cycling performance with higher capacity retention compared to pure Ge electrode: discharge capacity of ~ 1170 mAh g-1 after 10 cycles and good capacity retention are achieved.
