PAni/Si/G/C复合材料的制备及电化学性能
Synthesis and Electrochemical Performance of Si/C Composite Modified by PAni
摘要
Abstract
Silicon/carbon (Si/C) composite materials were prepared through high-energy ball milling and high-temperature solid-phase method, and then coated with thin polyaniline (PAni) film by oxidation. The microstructure and component of the composites were characterized by SEM, XRD, IR, TG, and the electrochemical performance was investigated by cyclic voltammetry (CV) and galvanostatic charge-discharge tests. The results showed that the surface of PAni/Si/G/C composite was coating with complete lamellar structure of PAni film. Its reversible capacity was 784 mAh · g-1 and 690 mAh · g-1 could be maintained after 50th charge-discharge cycles.关键词
