用电子显微镜和X射线衍射技术研究了电极板上活性物质硫酸铅微晶的成核和生长。结果如下：1.在阳极氧化的早期阶段，硫酸铅微晶优先在具有低折射率的Pb的晶体表面，特别是（001）和（111）面上成核，并且取决于放电条件而呈树枝状生长。它们之间的晶体学关系对于Pb的（001）面由Pb [100]//PbSO 4 [100]给出，对于Pb的（111）面由Pb [1 ~ O]//PbSO 4 [01 O]或[111]给出。2.作为活性材料的硫酸铅的晶体结构不能与其它类型的PbSO 4的晶体结构区分开。它没有转化为铅，即使在充满电的状态下，但形态变化可以看出，在这两种形式的硫酸铅。
Nucleation and growth of lead sulfate crystallites as the active material on an electrode plate were examined by electron microscopy and x-ray diffraction techniques. The results were as follows: 1. In the early stage of anodic oxidation, lead sulfate crystallites nucleate preferentially on the crystal surfaces of Pb having low indices, especially the (001) and (111) planes, and grow dendritically depending on the condition of discharging. The crystallographic relation between them is given by Pb [100]//PbSO4 [100] for the (001) plane of Pb, and Pb [l~ O]//PbS04 [OlO] or [111] for the (111) plane of Pb. 2. The crystal structure of lead sulfate as the active material could not be distinguished from that of the other type of PbSO4. It was not transformed to Pb even in the fully charged state, but a morphological change could be seen in both forms of PbSO4.
