Si and pyrolized PANI composites(Si/p-PANI) used as anode materials for lithium ion batteries, were prepared by ball-milling and high temperature pyrolysis at different temperatures,using nano-silicon as raw material and polyaniline(PANI) as carbon source. The structure, morphology and electrochemical properties of the Si/PANI and Si/p-PANI composites were characterized by XRD, SEM, TEM, FTIR, XPS, constant current charge-discharge and cyclic voltammetry(CV) methods. The results show that Si/p-PANI composit...
