CARBON MATERIAL FOR NONAQUEOUS SECONDARY BATTERY NEGATIVE ELECTRODE, NEGATIVE ELECTRODE FOR NONAQUEOUS SECONDARY BATTERY, AND NONAQUEOUS SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide: a nonaqueous secondary battery small in capacity loss in initial charge/discharge, good in initial charge/discharge efficiency, small in gas generation amount during initial charge/discharge and during high-temperature storage, excellent in safety and good in cycle characteristics; a negative electrode used in the nonaqueous secondary battery; and a carbon material used for manufacturing the negative electrode.SOLUTION: A carbon material for a nonaqueous secondary battery negative electrode contains a carbonaceous substance subjected to isotropic pressurization treatment and an organic compound having a basal adsorptive group and a cationic group.
