摘要
用CoCl_(2)·6H_(2)O、ZnCl_(2)、尿素(CO(NH_(3))_(2))、Zn(NO_(3))_(2)·6H_(2)O、Co(NO_(3))_(2)·6H_(2)O和购买的复合材料,对其电化学性能进行对比分析。结果表明:GO1的加入,增大了ZnCo_(2)O_(4)/GO1复合材料的比表面积,改善了ZnCo_(2)O_(4)材料的电化学性能;在电流密度为2A/g的条件下,采用溶剂热法和水热法制备的ZnCo_(2)O_(4)/GO1复合材料的比电容值分别是32.3F/g和18F/g,经500次循环实验后,这两种方法制备的复合材料的电容保持率分别为85.3%和80.2%。所以溶剂热法制备的ZnCo_(2)O_(4)/GO1复合材料的综合性能更好。
CoCl_(2)·6H_(2)O,ZnCl_(2),urea(CO(NH_(3))_(2)),Zn(NO_(3))_(2)·6H_(2)O、CO(NO_(3))_(2)·6H_(2)O and purchased composite materials were used,and their electrochemical properties were compared and analyzed.The results show that the addition of GO1 increases the speific surface area of ZnCo_(2)O_(4)/GO1 composite and improves the electrochemical properties of ZnCo_(2)O_(4);Under the current density of 2A/g,the specific capacitance of ZnCo_(2)O_(4)/GO1 composites prepared by solvothermal and hydrothermal methods is 32.3F/g and 18F/g respectively.After 500 cycles,the capacitance retention of the composites prepared by solvothermal and hydrothermal methods is 85.3%and 80.2%respectively.Therefore,the comprehensive properties of ZnCo_(2)O_(4)/GO1 composites prepared by solvothermal method are better.
