英文摘要	Germanium (Ge) nanocrystals combined with multiwalled carbon nanotube (Ge-MWCNT) composites were synthesized via a solvothermal approach and characterized through X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy and scanning and transmission electron microscopy (SEM and TEM). The electrochemical behaviour during lithium insertion and de-insertion was investigated by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and galvanostatic charge-discharge measurements. The as prepared Ge-MWCNT nanocomposite exhibits improved cycling performance with higher capacity retention than pristine Ge. The Ge-MWCNTs exhibit a discharge capacity of similar to 1160 mA h g(-1) after 60 cycles at a current rate of 0.1C. Furthermore, they showed an excellent rate performance at a current rate of 5C (where 1C is 1600 mA g(-1)) by delivering a specific capacity of similar to 406 mA h g(-1) over 400 charge-discharge cycles.
