摘要
用直接反应法制备了C/CuCl2 从 6 .3- 88.2的五种不同的CuCl2 -石墨层间化合物 .X射线粉末衍射分析指出它们分别为一阶、一二混阶、二阶和高阶 (大于二阶 )石墨层间化合物 ,Ic(°A)分别为 9.4 6、9.4 6 /11.6 3、12 .0 99、15.74、18.394 °A。通过循环伏安法对一阶、一二混阶层间化合物的电化学性能进行了研究 。
WT5BZ]Five graphite-CuCl 2 intercalation compounds with different compositions were formed by directly reacting with graphite and CuCl 2·2H 2O. They were indicated to be 1、1 2、2、3 stages respectively and have Ic°A of 9.46、9.46/11.63、12.09、14.94、18.39 by XRD. Their stabilities in air、 water、 NH 3(aq)、 EtOH、PC were examined. Their circle V-A curves gave some information about their electrochemical properties, when two of them, with 1 and 1 2 stages, were used as cathode material in LiClO 4-PC non aqueous systems. The ability of recharging of the Li-cell with Cu 2 used as cathode material was tested, which showed gave a good result. [WT5HZ]
