| Abstract: | The composite hydrogen storage materials of carbon nantube-MmNi3.6Co0.7Al0.3Mn0.4 were synthesized firstly by ball milling method under different conditions. The electrochemical properties of carbon nantube-MmNi3.6Co0.7Al0.3Mn0.4 have been investigated in this paper. The discharge capacities of the carbon nantube-MmNi3.6Co0.7Al0.3Mn0.4and MmNi3.6Co0.7Al0.3Mn0.4 electrodes were measured to be 320 and 270mAh/g, respectively, under a current density of 250mA/g. The electrochemical properties of carbon nantube-MmNi3.6Co0.7Al0.3Mn0.4 electrode have been studied by cyclic voltammetry. It shows that the composites of carbon nantube & MmNi3.6Co0.7Al0.3Mn0.4 accelerate hydrogen adsorption. |
