<P>PROBLEM TO BE SOLVED: To provide secondary battery's positive electrode materials having a large electric chargeable quantity and causing less capacity deterioration due to repeat of charge and discharge in a battery which employs a sulfur contained compound causing a redox reaction through cleavage-recombination in a disulfide linkage as an electrode active material, its manufacturing method and a secondary battery using them. <P>SOLUTION: The secondary battery's positive electrode material includes sulfur contained compounds (for example, 2, 5-dimercapto-1, 3, 4-thiadiazole) 1a, 1b in the pores of a single layer carbon nano-tube 2. <P>COPYRIGHT: (C)2007,JPO&INPIT |
