AMORPHOUS CARBON MATERIAL FOR NEGATIVE ELECTRODE OF LITHIUM ION SECONDARY BATTERY AND METHOD FOR PRODUCING THE SAME

摘要

The amorphous carbon material for the negative electrode of a lithium ion secondary battery of the invention has a true density of 1.800-2.165 g/cm 3 , but has a true density of 2.255 g/cm 3 or greater when subjected to graphitizing in an inert gas atmosphere at a temperature of 3000°C.
