研究了由Ｃｏ取代Ｎｉ位置的Ｎｉ（ＯＨ）２电极，由χ射线衍射测定了其结构与α－Ｎｉ（ＯＨ）２相同，且能在碱液中及电化学循环时稳定存在。放电结果表明，充放电循环过程中，电子转移数目大于１（不同于以往在Ｎｉ（Ⅱ）与Ｎｉ（Ⅲ）间进行），在本实验中最高可达１３８。实验制得的电极和β－Ｎｉ（ＯＨ）２电极相比，具有较小的界面转移阻抗和较高的充电效率，且具有良好的机械性能。本文还对实验结果和可能的机理进行了简要的分析和探讨。
The Ni (OH) 2 electrode with Ni replaced by Co was studied. The structure of Ni (OH) 2 electrode was the same as that of α-Ni (OH) 2 by X-ray diffractometry and was stable in alkaline solution and electrochemical cycling. The discharge results show that the number of electron transfer during charge and discharge cycles is greater than 1 (different from the previous case between Ni (Ⅱ) and Ni (Ⅲ)) and up to 138 in this experiment. Compared with β-Ni (OH) 2 electrode, the experimentally prepared electrode has a smaller interfacial transfer resistance and a higher charging efficiency, and has good mechanical properties. This paper also briefly analyzes and discusses the experimental results and possible mechanisms.
