摘　　要：采用简单的液相共沉淀法制得储铝超级电容器电极复合材料铁氰化铜钾{K_xCu[Fe(CN)_6]_x},通过XRD表征了样品的结构,通过循环伏安(CV)测试、恒流充放电测试分别研究了它的电化学性能。结果表明:在1mol/L硝酸铝[Al(NO_3)3]电解液中,K_xCu[Fe(CN)_6]_x的比电容高达592.8F/g,循环10次后,仍能达到初始电容的73%左右。KxCu[Fe（CN）6]x was synthesized using liquid-phase coprecipitation method.X-ray diffraction（XRD）was used to detect the structure of KxCu[Fe（CN）6]x.The electrochemical performance of KxCu[Fe（CN）6]x was studied in1 mol/L Al（NO3）3 electrolyte by means of cyclic voltammograms（CV）and galvanostatic charge/discharge measurement.The experimental results indicated that the specific capacitance of KxCu[Fe（CN）6]x can reach 592.8 F/g.Moreover,the specific capacitance of KxCu[Fe（CN）6]x was remain about 73% after 10 cycles.
