MATERIAL FOR NEGATIVE ELECTRODE OF LITHIUM SECONDARY BATTERY, METHOD FOR PRODUCTION THEREOF AND LITHIUM SECONDARY BATTERY USING THE SAME

摘要

A carbon material for a lithium secondary battery, in which the edge parts o f the crystals of a carbon material which is the core material of the cathode material are partially or entirely coated with a carbon material and the crystals have nearly spherical or elliptic shapes. There are also provided a process for manufacturing the carbon material, and a lithium secondary battery using the carbon material as a component.
