摘　　要：通过固相反应制得用于MnO2 电极物理改性的钙钛矿型PbTiO3 。循环伏安和恒流放电测试表明 :在w (KOH) =40 %的电解质溶液中 ,PbTiO3 参与了MnO2 电极反应 ,改善了MnO2 的放电机理 ,使MnO2 电极的放电容量平均提高 3 0 %以上。Perovskite PbTiO3 was prepared by solid phase reaction. PbTiO3 modified MnO2 electrodes were physically fabricated and their electrochemical properties were studied by cyclic voltammetry and galvanostatic charge/ discharge experiments.The results indicated that PbTiO3 was involved in MnO2 electrode reaction.The discharge capacity of MnO2 electrodes modified with 5.0% PbTiO3 was in average 30% higher than that of IC.No.1 MnO2 sample in w(KOH)=40% electrolyte.
