摘      要：Carbons pyrolyzed at temperature ranging from 500℃ to 1 000℃ are premising materials for high-energy density lithium batteries. These carbons not only possess a capacity higher than the theoretical value of graphite, but also display a different electrochemical behavior from that of graphite.Mechanisms now available for this phenomenon are reviewed after the presentation of mechanism of lithium intercalation in graphite. Based on the recent research, a new model for lithium insertion in carbons pyrolyzed at low temperature and some ideas for further study are proposed.
