CARBON MATERIAL FOR NON-AQUEOUS SECONDARY BATTERY, ANODE USING SAID CARBON MATERIAL, AND NON-AQUEOUS SECONDARY BATTERY

摘要

This invention aims to provide a carbon material for a nonaqueous secondary battery having a high capacity and excellent charging/discharging load characteristics, which is used as a negative electrode material for a nonaqueous secondary battery. This invention relates to a carbon material for a nonaqueous secondary battery, which has a specific (1) Raman R value, (2) N atom concentration/C atom concentration ratio, and (3) S atom concentration/C atom concentration ratio.
