An electrode active material has,as the main component, a mixture of an organic compound containing a rubeanic acid indicated by the following general formula in the structural unit and oxamide. In the formula, n indicates an integer between 1 and 20, and R1 - R4 indicate hydrogen atoms, halogen atoms, or a prescribed substituent group such as a hydroxide group, a 1-3C alkyl group, an amino group, a phenyl group, a cyclohexyl group, or a sulfo group. A positive electrode (4) contains this electrode active material. As a result, the electrode active material, an electrode, and a secondary battery are achieved that have high energy density, high output, and excellent cycle characteristics whereby there is small deterioration in capacity even in repeating charging and discharging. |
