摘要

通过溶胶-凝胶法制备了Ni-Mg-O及作为对照物的NiO样品,研究了其电化学嵌锂性能,并对样品进行了XRD结构表征,Rietveld精化以及贮锂性能测试.结果表明:Ni-Mg-O电极由于Mg的掺入而抑制了其中Ni2+的还原,导致材料的比容量降低.但同时又因该样品形成均一的固溶体使得NiO分散效果较好,从而改善其循环性能.

Abstract

In the present work, Ni0.67Mg0.33O and NiO were produced by sol_gel method, and characterized by XRD, a rietveld refinement and the discharge/charge test.It was found that the magnesium_doping restrained the reduction of Ni and decreased the reversible capacity for the sample of Ni0.67Mg0.33O. But the formation of the solid solution after the magnesium_doping facilitated the high dispersion of NiO, and accordingly improved the electrochemical performance.
