Unlocking lithium ion conduction in lithium metal fluorides
Quasi-crystalline lithium metal fluorides prepared by mechanochemical synthesis exhibit up to 300-fold higher σ than their crystalline counterparts. The increase in Li+-ion diffusivity in materials with decreased crystallinity can be primarily attributed to the introduction of amorphous hetero-interphases, which provide faster Li+ diffusion pathways …
Unlocking lithium ion conduction in lithium metal fluorides
