PROBLEM TO BE SOLVED: To provide a carbon material capable of obtaining a secondary battery high in capacity and small capacity loss at the initial charge and discharge when used as an electrode of the secondary battery and to provide a secondary battery using the same. SOLUTION: The carbon material is a hear treated mixture of a thermosetting resin and a metallic salt, which has the atomic ratio of nitrogen/carbon (N/C) atom of 0.001-0.03, the interval between lattices (doo2 ) of 3.625-4.00Å, 1-25m<2> /g specific surface area by BET method and total fine pore volume of 0.03-0.3ml/g. The secondary battery uses the carbon material as the electrode. |
