| 中文摘要: |
| 目的 提高锂离子电池锗基材料的电化学性能。 方法 采用电泳和离子液体电沉积制备乙炔黑/ 锗负极材料,用 SEM,Raman 和充放电循环等手段表征其结构和性能。 结果 乙炔黑/ 锗负极材料在0. 2C 倍率下循环 100 次,比容量依然可达到 600 mAh/ g 以上。 结论 乙炔黑/ 锗负极材料的电化学性能明显优于单独锗材料和碳材料。 |

| 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. |
