- 摘要:
- 采用恒电流沉积法,选用适宜的添加剂和络合剂,成功地从水溶液中沉积出有金属光泽、致密、附着力好的镁基储氢合金膜,探讨了温度及镀液成分对合金储氢性能的影响。X-射线衍射分析显示沉积层中含有非晶态M g-N i合金相和微晶态M g相。原子吸收光谱分析表明沉积合金中M g的质量分数达到8.57%,合金的放电容量最高为75.547 mA h/g。
- Abstract:
- Smooth,adhesive,uniform and metallic luster Mg-based hydrogen storage alloy films were electrodeposited from aqueous solution with optimal complexing agent and addition agent at constant current density.The influence of bath composition and temperature on the hydrogen storage property of the alloys was described.XRD shows that there is amorphous Mg-Ni phase and microcrystalline Mg phase in the electrodeposites.AAS analysis indicates that the mass percent of Mg is up to 8.57%,and the maximum discharge capacity of the deposit is up to 75.547(mAh/g.)
