摘要
大多数已发表的LiMn2O4尖晶石晶胞参数未经校正,不能定量揭示晶体的结晶程度、更不能直接对比。论述了一种以天然石英作为内标标准物质、通过粉晶X射线衍射光谱法(XRD)精确测定锰酸锂尖晶石晶胞参数的方法,测定的各种锰酸锂尖晶石的晶胞参数可以直接对比,能方便了解彼此晶体结构的差异及其对锰酸锂电化学性质的影响。
The lattice parameters data of LiMn204 spinel in most publications were not corrected so that they can neither reveal the crystallinity degree, nor compare with each other. A way to precisely determine the lattice parameters of LiMn204 spinel by taking quartz as internal standard substance with powder XRD technology was revealed. The corrected lattice parameters of LiMn204 spinel could well reveal the difference between their crystal structures, when they compared with each other.
