Co(OH)_2的电化学性能研究

合成了结晶程度较高的Co(OH)2,并对其电化学性能进行了研究。充放电实验表明:Co(OH)2具有一定的放电比容量:98.4mAh/g,多次充放电实验表明它的容量较为稳定。循环伏安实验表明:氢氧化钴电极具有一定的可逆性。X射线衍射实验结果说明:电极反应是在CoOOH和Co(OH)2之间进行的。通过对氢氧化钴的电化学性能研究,能进一步了解Co(OH)2作为添加剂的作用机理。

Studies on the Electrochemical Properties of Cobalt Hydroxide

Crystalline Co(OH)2 was synthesized and its electrochemical characters were studied. The charge discharge experiments show that cobalt hydroxide electrode has a comparatively stable capacity of discharge, which is about 98.4 mAh/g. The experiments of cyclic voltammety show that the cobalt hydroxide electrode is reversible. The result of X ray diffraction shows that the electrode reaction takes place between CoOOH and Co(OH)2. The function of cobalt hydroxide, as an electrode additive, is known more clearly through the studies of its electrochemical properties.
