Garnet-type structured lithium ion conducting ceramics represent a promising alternative to liquid-based electrolytes for all-solid-state batteries. However, their performance is limited by their polycrystalline nature and inherent inhomogeneous current distribution due to different ion dynamics at grains, grain boundaries, and interfaces. In this study, we use a …
Higher power Li ion rechargeable batteries are important in many practical applications. Higher power output requires faster charge transfer reactions in the charge/discharge process. Because lower activation energy directly correlates to faster Li ion diffusion, the activation energy for ionic diffusion throughout the electrode materials is …

Quirk and Dawson looked at modelling three Li-ion conductors—an anti-perovskite oxide (Li 3 OCl), a thiophosphate (Li 3 PS 4), and a halide (Li 3 InCl 6) []. They demonstrated the oxide to have worse ionic conduction across grain boundaries than within the bulk, as expected, but found the effect to be less severe in the halide, much like in …
