| Abstract: | 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] |
