椭圆形管式密封铅酸蓄电池电极表面电流分布的实验研究(二)

THE EXPERIMENTAL STUDY OF THE CURRENT DISTRIBUTION ON THE ELECTRODE SURFACE OF A NEW SEALED OVAL TUBULAR LEAD - ACID BATTERY(2)

本文用化学分析方法研究了在固定的电流强度50A,不同的放电深度(100％,50％,20％)放电后椭圆形密封铅酸蓄电池正极板的电流密度分布。研究结果表明:整个极板各个区域电流密度的分布是不均匀的,主要表现为极耳附近以及极板的边缘电流密度较大,且放电深度为100％时这种现象更明显。

This paper studies the electrical distribution on positive electrode surface of sealed lead -acid battery when the electrical current intensity is 50A and the discharge depth is 100%,50% and 20% respectively. The results show that the current distribution is not even. The current density on the edge of the electrode surface is bigger than other areas,and that this effect is more obvious when the discharge depth is 100%.
