中文摘要: |
采用分子动力学模拟方法探讨了锂离子水合团簇分别在氟化锂、氯化锂、碘化锂晶体
表面的扩散。分别构建1 至4 个水分子的4 种锂离子水合团簇,观察不同时刻锂离子水合团簇的分
布状况,统计了锂离子水合团簇在氟化锂晶体表面的扩散系数。结果表明锂离子水合团簇在不同
的卤化锂晶体表面的扩散不同,并且不同水分子个数的锂离子水合团簇在氟化锂晶体表面的扩散
的差异很大。 |
英文摘要: |
Molecular dynamics simulation was applied to study the diffusion of lithium ion hydrates on surface of LiF, Li⁃
Cl and LiI crystals. The lithium ion hydrates which contain 1 to 4 water molecules were constructed. The distributions of
lithium ion hydrates at different moments were observed and the diffusion coefficients of lithium ion hydrates on surface of
LiF crystal were calculated. The results showed that the diffusion of lithium ion hydrates on surface of different lithium ha⁃
lide crystals were different. Besides, the diffusion of lithium ion hydrates containing different water molecules on the sur⁃
face of LiF crystal were quite different. |
