| 摘 要： | 利用溶胶凝胶法制备了新型锂离子二次电池正极材料LiNi1-xAlxO2(x=0,0.1～1.0)固溶体,X射线衍射结果表明,在0≤x≤1范围内,材料均为具有α-NaFeO2型结构的LiNi1-xAlxO2固溶体单相.随着Al固溶量的增加,晶胞参数发生变化,a轴缩短,c/a比增大,晶胞体积V0减小,材料的层状属性更加明显.

| Abstract: | This paper covers the results of structural study of solid solution of LiNi 1-x Alx O2( x=0-10) via Xray diffraction. It is observed that the single phase solid solution with α NaFeO2 structure is formed for the whole concentration range(0≤x≤1). Lattice parameter, a decreased, c/a increased, and cell volume decreased with the increasing of Al concentration. The layered characteristics becomes more and more strong with the increasing of Al concentration. |
