| 摘 要： | 用交流阻抗(EIS)、线性扫描(LSV)、循环伏安(CV)、动电位阻抗法(ACV)研究铅银和铅银镧合金作为正极板栅的性质.结果发现:Ag的添加可能除低正极氧超电势,增加正极的析氧量;La则可能抑制氧气的析出.并且Ag、La的添加可抑制阳极Pb(II)膜的生长,改善深放电时铅合金上所形成的阳极Pb(II)膜的阻抗特性,抑制铅的阳极腐蚀. |

| Abstract: | The methods of a.c.impedance spectroscopy, linear sweep voltammetry, cyclic voltammetry,and AC voltammetry were applied to study the properties of lead-silver and lead-silver-lanthanum alloys. The experiment results show that the addition of silver leads to the decrease of the oxygen overpotential and increase of the oxygen evolution rate, but lanthanum can inhibit the oxygen evolution rate, and silver and lanthanum can inhibit the anodic corrosion of lead and decrease the impedance of anodic Pb(II)and PbO2... |
