Abstract

We have studied microstructure of carbn fiber and graphite using scanning electron microscope, x-ray diffractommetry and x-ray photoelectron spectroscopy. According to the results, intercalation of lithium ion affected formation of film on carbon surface and changed structural parameter. Also, we found that film on carbon surface included lithium ion. And, the results of XPS indicated that surface of lithiated carbon materials existed P and F consisting electrolyte. Thus, We expected electrolyte cointercalated with lithium.
