Extremely Fast Interfacial Li Ion Dynamics in Crystalline LiTFSI Combined with EMIM-TFSI.

Materials providing fast transport pathways for ionic charge carriers are at the heart of future all-solid state batteries that completely rely on sustainable, nonflammable solid electrolytes. The mobile ions in fast ion conductors may take benefit from structural disorder, cation and anion substitution, or dimensionality effects. While these effects concern the bulk regions of a given material, one may also manipulate the surface or interfacial regions of a polycrystalline poorly conducting electrolyte to enhance its transport properties.

Synthesis, Crystal Structure, and Stability of Cubic LiLaZrBiO.

Li oxide garnets are among the most promising candidates for solid-state electrolytes in novel Li ion and Li metal based battery concepts. Cubic LiLaZrO stabilized by a partial substitution of Zr by Bi has not been the focus of research yet, despite the fact that Bi would be a cost-effective alternative to other stabilizing cations such as Nb and Ta. In this study, LiLaZrBiO (x = 0.

"Ionic liquids-in-salt"--a promising electrolyte concept for high-temperature lithium batteries?

A novel electrolyte concept for lithium-ion batteries, termed "ionic liquid-in-salt", is introduced. Our feasibility study on (1 - x)EMIMTFSI:(x)LiTFSI, 0.66 ≤ x ≤ 0.
