摘要

A new composite anode material of Ag and polymeric carbon was prepared by heat-treating the mixture of polyacrylonitrile and AgNO3. They were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), electrochemical impedance spectroscopy (EIS) and electrochemical measurements. It was found that the addition of Ag was favorable for the improvement of electrochemical performance of the composite in comparison with the virginal polymeric carbon. These improvements were due to an increase of electronic conductivity, alloying of lithium with Ag and smaller particle size of the composites. The optimal amount of Ag addition is 5% based on the molar ratio of the monomer unit.
