Outline of Final Research Achievements |
Iron negative electrode for alkaline secondary batteries suffers fromits low utilization due to passivation. In order improve the utilization of iron, composite electrodes based on nano-particles of iron species and carbon nano-fiber (CNF). The sol-gel precipitation compositization is favorable for iron utilization until 0.45 mass ratio of iron, while the mixing of nano-sized Fe3O4 with CNF is effective for higher iron loading. The iron content above where iron utilization abruptly increase exists regardless of the compositizing method. Further investigation on this phenomenon indicates some accerelation effect of intermediate ferrous species on the oxidation (discharge) process.
