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 本文利用电化学扫描方法研究铅酸蓄电池正负极板在化成过程中电流密度和电位分布及化成对极板电性能的影响。同时分析了正负极添加剂的性质及其对极板性能的影响。
During the formation , the positive plates with red lead and bapbo3 additives are easier formed than that without additive , so the current and potential distributions on the plates with additives are more uniform than that without additives in the early stage of the formation . these distributions on the plate with red lead are the most uniform , and the polarization is the smallest 在正极板化成过程中,含红丹和铅酸钡铅膏的正极板比不含添加剂的正极板更容易化成,所以在化成初期含添加剂正极板的电流密度和电位分布比不含添加剂正极板上的电流密度和电位分布更均匀。
But the preparation of high performance anode coating containing pt ? has not been completely researched yet . thermal decomposition and electrochemical reduction mechanism is discussed in this dissertation using thermodynamics balance and e - ph figures . an improved thermal decomposition technique has also been developed for preparing titanium - based electro - catalytic layers 本文结合热力学平衡和电位? ph图,讨论了热分解-电化学还原法制备钛基含铂涂层的原理,并采用一种改进的间换法工艺,制备了高活性的钛基含铂( pt ~ 0 )电催化涂层。
