【摘要】 应用循环伏安法和掠射式椭圆偏振谱学法,研究了Pb在H2SO4电解液中阳极氧化生成PbSO4 的过程。实验表明:由于半渗透PbSO4钝化膜的形成和溶解,在铅阳极过程中有明显的电化学振荡现象产生,它对铅酸蓄电池的充放电性能有一定影响。更多还原

【Abstract】 Graze ellipsometry and cyclic voltammetry have been used to study the anodic oxidation process of Pb into PbSO4 in H2SO4 solution. Experiments indicated that apparent electrochemical oscillation occurs in the process which is attributed to the formation and dissolution of the passivation film on the Pb electrode.更多还原
