摘要

锂石榴石氧化物是一类快速离子导体，在固体状态下具有可观的锂离子电导率，使其成为全固态电池电解质的有希望的候选者。在它们的结构中，锂部分(连同空位)分布在多个晶体学上不同的位置，就像其他快离子导体一样。这种无序对锂离子的扩散率和电导率等输运性质有很大的影响。我们回顾了原子模拟研究与互补的实验研究，这些研究提供了锂石榴石氧化物中锂输运现象的原子尺度可视化和洞察力。

Transport in Lithium Garnet Oxides as Revealed by Atomistic Simulations

Lithium garnet oxides are a family of fast-ion conductors with appreciable lithium ionic conductivity in the solid state, making them promising candidates as electrolytes for all-solid-state batteries. In their structures, lithium is partially (along with vacancy) distributed among more than one crystallographically distinct sites, just as with other fast-ion conductors. This disorder has a great influence on lithium's transport properties such as diffusivity and ionic conductivity. We review atomistic simulation studies in conjunction with complementary experimental investigations, which offer atomic-scale visualization of and insight into lithium transport phenomena in lithium garnet oxides.
