1. 毕业设计（论文）的内容和要求

镁基储氢合金因其具有储氢量大(3.6wt.%，mg2ni理论容量999mah/g，分别是ab5型合金的2.6倍和ab2型合金的1.6倍)、价格低廉、资源丰富，环境友好等优点，并成为国内外新的研究热点之一。

作为mh-ni电池负极材料，镁基非晶态合金拥有良好的应用前景，mg2ni合金电极的理论放电容量达到999 mah/g，是作为二次电池的理想材料，但是mg2ni合金电极电化学动力学性能较差，在强碱溶液中活性物质的腐蚀、氧化以及在充放电过程中粉化都较严重，导致其有效容量低，循环寿命差，而具有非晶结构的mg-ni合金在室温下能够可逆充放电，初始放电容量也较晶态的mg-ni合金高，因而具有广阔的发展前景。

本课题通过合成mg-ce-ni非晶态合金来作为镍氢电池的负极材料，并通过不同的方式对其进行改性处理，以便获得优异的电化学性能。
