Low-temperature pyrolytic carbon materials have lithium insertion capacity higher than the theoretical capacity of graphite, which shows the electrochemical insertion of lithium which is different from that of graphite and is expected to be used in high-energy lithium batteries.Based on the review of lithium insertion mechanism of graphite intercalation compounds There are various models about the mechanism of low temperature pyrolytic carbon lithium insertion, and the emphasis is put on the rationality and inadequacies of each lithium insertion model.According to the existing research results, a new low temperature pyrolytic carbon lithium insertion model is proposed, and further research on low temperature heat Conceive of the mechanism of deintercalation and lithium insertion.
