Abstract：
 The present invention relates to a carbonaceous lithium ion cell negative electrode material with core-shell structure and its preparation method, belonging to the field of carbon material and chemical power supply technology. The described negative electrode material is formed from core portion and shell portion. The core portion is graphite obtained after the graphite intercalation compound is disintercalated, the shell portion is amorphous carbon obtained by pyrolysis of organics. Said invention also provides the concrete steps of its preparation method.
