Abstract
To provide a carbon material from which lithium battery whose discharge capacity is large and which is good in terms of output characteristic is obtainable. A carbon material according to the present invention for lithium battery is characterized in that a BET specific surface areas is 10-1,000 m2/g; a carbon interlayer distance is 0.350-0.380 nm; and a carbon intensity is 2,000 cps or more. In the carbon material according to the present invention for lithium battery, a high output and a low retention are obtainable when forming lithium battery.
