摘要：A needle coke was graphitized at different heat treatment temperature (2000℃ to 3000℃). The electrochemical intercalation mechanism of Li into the graphitized coke has been studied in Li｜1mol*L-1 LiClO4+ethylene carbonate/diethylene carbonate｜graphite cells, using an in-situ X-Ray diffraction (XRD) technique. The study of Li-C intercalation processes of the graphitized coke reveals that there are three major types of intercalation behavior. The first is uniformly intercalated at all Li-C compounds in graphitized coke heated at 2250℃; the second is obviously staging phenomenon during intercalating for the graphitized coke heated at 2750℃; the third is cointercalation of
