摘要
Abstract
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 struc-ture and electrochemical properties were characterized by electron microscopy, Raman spectroscopy and constant current charge-discharge 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 acety-lene black by itself as anode electrode material.关键词
