Abstract: The intercalation of lithium into benzene carbon black was investigated in nonaqueous solution by cycling voltammetric methods. The results showed that the exist of several irreversible reactions during the first cathodic scanning was due to the decompositions and intercalations of the solvents in the electrolyte. By increasing the content of graphitization region in the benzene carbon black, the intercalation and deintercalation of lithium could occur at about 0.1 V vs lithium and make it possible to change the lithium in the lithium secondary batteries with this kind of carbon.
