摘    要:采用气体收集、线性电位扫描和交流阻抗等方法,研究了不同锡含量的铅锡合金电极在H4SO4中的析氧行为.随着锡含量的增加,氧气析出的体积逐渐减少,析氧电流逐渐减小,铅锡舍金电极上的析氧电化学电阻增大,电容减小.掺锡抑制了氧气的析出.

关 键 词:铅锡合金  铅酸电池  析氧

Abstract:The oxygen evolution behavior of Pb-Sn alloys with different tin content in H2SO4 was studied by measuring the gas collection,linear sweeping voltammetry and AC impendence.With the increasing of tin content,the volume of oxygen evolution decreased,the oxygen evolution current decreased,the electrochemical resistance of oxygen evolution of Pb-Sn alloy electrode increased and the capacitance decreased.The doping of tin inhibited the oxygen evolution.
Keywords:Pb-Sn alloy  lead acid battery  oxygen evolution
