With the development of the technology and the automation of the modern industry, finding a new kind of energy storing device gradually occupies a significant position. The supercapacitor takes up scientists’ eyes, because of its advantages of high watt density, long servicing life and non-pollution. However, there is also some barriers blocking the way of the forward development. In this project, we use MOF-5 as the electrode material, combining with some other metal atoms to enhance its specific capacitance. Through researching, we found that using Ni as the adding atom has a markable difference. It can improve the conductivity of the electrode effectively, then enhancing the specific capacitance. Finally, we measured the data of the supercapacitor using Ni-MOF-5 as the electrode materials under different scanning speed. Then we got the specific capacitance respectively: 105 under 50 , 78 under 100 , 44 under 500 , 35 under 1000 .
