摘　　要：超级电容器是一类新型的绿色能源储存装置,电极材料是超级电容器最重要的组成部分,多金属氧酸盐具有可逆快速转移电子、成本低廉、电子海绵的特性。将其与乙炔黑和氧化石墨烯混合制备成复合电极材料负载在玻碳电极上探究超电性能。结果表明,当多酸与乙炔黑质量比为1:1,氧化石墨烯浓度为3 mg/mL,移取混合物体积20μL,电流密度为0.5 A·g^(-1)时,材料充放电时间可达135秒,比电容大小为33.61 F·g^(-1),恒流充放电1000圈后,电容保持率仍然可以达到97.6%,说明此复合电极材料具有较好的超电性能。Supercapacitor is a new type of green energy storage device.Electrode material is the most important component of supercapacitor.Polyoxometalate has the characteristics of reversible and rapid electron transfer,low cost and electron sponge.The composite electrode material was prepared by mixing it with acetylene black and graphene oxide and loaded on the surface of glassy carbon electrode to investigate the supercapacitor properties.The results show that when the mass ratio of polyoxometalate to acetylene black is 1:1,the graphene oxide concentration is 3 mg/mL,the mixture volume is 20μL and the current density is 0.5 A·g^(-1),the charge and discharge time of material can reach 135s,the specific capacitance is 33.61 F·g^(-1) and the capacitance retention rate can still reach 97.6%after 1000 cycles of constant current charge and dis-charge.It shows that the composite electrode material has good supercapacitor properties.
