This paper researches on the practical current and potential distributions on the positive and negative plates of automotive batteries in the course of their formation processes by the means of an in situ electrochemical scan , and then studies the influences of the formation and also the additives on the performance of the automotive plates 本文利用電化學掃描方法研究鉛酸蓄電池正負極板在化成過程中電流密度和電位分布及化成對極板電性能的影響。同時分析了正負極添加劑的性質及其對極板性能的影響。

When formed for 8h , because most of paste on the negative plate has converted into lead , the polarization increases and the potential changes greatly , these distributions on the two kinds of negative plates become non - uniform again 當化成8h時,由于負極板上的鉛膏大部分轉化為鉛,極化上升,電位變化很大,所以兩種負極板上電流密度和電位分布又變得不均勻。

At the end of the formation , both current and potential distributions are uniform . however , their distributions on the negative plate with the expanded grid design are a little more uniform 化成結束時電流密度和電位分布都比較均勻,且拉網式負極板比輻射式負極板更均勻。

The distributions of current density and potential on the negative plates with the radiational or expanded grid designs are more uniform than those on the positive plate 輻射式和拉網式負極板在化成開始時電流密度和電位的分布都比正極板上分布均勻得多。

An element is assembled from one positive group “nested“ in a negative group, with negative plates always on the outside, and positive and negative plants in alternating position . 一個極群組是把正極群“套”進負極群內組裝而成的,負極板總是在外側,而且正、負極交錯放置。

On the other hand, prepared negative plate expander is commercially available . 另一方面,在商業上可購到現成的負極板膨脹劑。

The chipped area is not between the lugs of adjacent positive and negative plates . 破碎部分不在相鄰的正負極耳之間。

Negative plates generally used litharge as the lead oxide material . 負極板一般用氧化鉛做活動性物質材料。
