摘　　要：为了提高膏式镉电极充放电效率,采用循环伏安及充放电实验等方法,研究了La_2O_3、Nd_2O_3、Gd_2O_3、Dy_2O_3、Y_2O_3等稀土氧化物添加剂对镉负极电化学行为及电池容量的影响.实验结果表明,Dy_2O_3、Y_2O_3对提高镉负极活性物质的利用率有较好的作用.In order to improve the charge and discharge efficiency of pasted Cadmium electrode,effect of rare - earth oxide additives such as La2 O3, Nd2O3, Gd2 O3, Dy2 O3, Y2O3 on the electrochemical pmperty and capacity of Cadmium electrode were studied, by means of cyclic voltammetry and recharging/discharging experiment. The result of this experiment showed that Dy2O3 and V2O3 could enhance capacity of discharging and active material utilization.
