摘要：

Layered LiNi1/3Co1/3Mn1/3O2 was synthesized by co-precipitation method, and a series of polypyrrole-LiNi1/3Co1/3Mn1/3O2 composites were then prepared by polymerizing pyrrole monomers on the surface of LiNi1/3Co1/3Mn1/3O2. The bare sample and composites were subjected to analysis and characterization by the techniques of scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD). The electrochemical properties of the composites were investigated with galvanostatic charge-discharge test and AC impedance measurements, which show that the formed coats of polypyrrole (PPy) significantly decrease the charge-transfer resistance of LiNi1/3Co1/3Mn1/3O2. And the composite containing 2.0 wt% PPy exhibits a good electrochemical performance, its specific discharge capacity is 182 mAh g(-1) at 0.1C rate and voltage limits of 2.8-4.6V, while the capacity of the bare sample is only 134 mAh g(-1).
