摘要：

本文首次研究了碳纳米管-MmNi3.6Co0.7Al0.3Mn0.4复合储氢材料的制备及其电化学性能,在250mA/g放电的条件下,其电化学储氢量达到320mAh/g,相同条件下MmNi3.6Co0.7Al0.3Mn0.4储氢量为270mAh/g.通过循环伏安法研究氢在复合电极上电化学特性表明,碳纳米管与MmNi3.6Co0.7Al0.3Mn0.4的复合促进了氢的吸附.

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.
