| Abstract: |
| Objective To improve the electrochemical performance of the germanium materials of lithium-ion batteries. Methods Germanium nanoparticles (Ge-NPs) and acetylene black anodes were fabricated through electrodeposition of Ge in the new-genera-tion ionic liquids on the surface of acetylene black which was electrophoretically deposited on a copper current collector. The structure and electrochemical properties were characterized by electron microscopy, Raman spectroscopy and constant current chargedischarge methods. Results The acetylene black-Ge nanocomposite exhibited the electrochemical cycling properties of over 600 mAh/ g at 0. 2C after 100 cycles. Conclusion The electrochemical performance of composite was obviously better than Ge or acetylene black by itself as anode electrode material. |
