| Abstract: | Perovskite type La0.6Ca0.4CoO3 as a catalyst of oxygen reduction for Al-air battery was prepared,and the structure and performance of the catalysts were examined by X-ray diffraction (XRD),and thermogravimetry(TG).The mixed catalysts doped with different metal oxides were studied. The electrochemical performances of the materials were obtained by measuring the cathodic polarization curves in 6 mol/L KOH and testing the discharge performance of the assembled Al-air battery. The results show that the perovskite type catalyst doped with metal oxide is an excellent catalyst for Al-air battery,can promote the reduction of oxygen and improve the properties of Al-air battery effectively. |
