| 摘 要： | 利用氢化燃烧合成法与机械球磨法复合制备镁基储氢电极合金,研究了加镍球磨对合金的影响.XRD结果表明:加镍球磨后,合金结构由晶态转变为非晶态.电化学测试结果表明:氢化燃烧合成产物加镍球磨后,电化学性能有所改善,如添加镍粉球磨后,合金电极的放电比容量为580.06 mAh/g,循环20次后为346.24 mAh/g,容量保持率约为60%.

| Abstract: | Mg-based hydrogen storage electrode alloy was prepared by hydriding combustion synthesis(HCS) method combined with mechanical ball-milling(MM) method.The effects of MM added with Ni powders to the alloys were investigated.The XRD results showed that the structure of the alloys changed from crystallite to an amorphous-like state after MM added with Ni powders.Electrochemical test results showed that the electrochemical performance of the HCS+MM(Ni) products was improved.A specific discharge capacity of 580.0... |
