ABSTRACT A secondary battery comprising a rechargeable positive electrode, a rechargeable lithium-containing negative electrode, a separator allowing the positive electrode and negative electrode to be separated from each other, and organic electrolyte solution for connecting the positive electrode and negative electrode. The negative electrode includes a complex substance having a carbon molded article made of carbon fiber or carbon powder having an interfacial distance (d002) of 3.38 to 3.56 Angstroms(.ANG.) as measured by X-ray diffraction analysis using silicon as standard material, wherein lithium have been absorbed into the carbon molded article beforehand. The above value of interfacial distance corresponds to 3.36 to 3.48 .ANG. as measured by X-ray diffraction analysis using no standard material.
