Abstract
A superior lithium secondary battery having high total discharge capacity, high effective discharge capacity, high total discharge efficiency, and high effective discharge rate can be obtained by using, as a carbon electrode for a lithium secondary battery, a carbon for a lithium secondary battery obtained by successively conducting a halogenation treatment, a dehalogenation treatment, and a pore adjustment treatment on a dry-distilled charcoal, or by successively conducting a crushing treatment, a molding treatment, and a carbonization treatment on a dry-distilled charcoal.
