Stabilizing the Li_1.3 Al_0.3 Ti_1.7 (PO₄ )₃ |Li Interface for High Efficiency and Long Lifespan Quasi-Solid-State Lithium Metal Batteries.

ABSTRACT: To tackle the poor chemical/electrochemical stability of Li_1+x Al_x Ti_2-x (PO₄ )₃ (LATP) against Li and poor electrode|electrolyte interfacial contact, a thin poly[2,3-bis(2,2,6,6-tetramethylpiperidine-N-oxycarbonyl)norbornene] (PTNB) protection layer is applied with a small amount of ionic liquid electrolyte (ILE). This enables study of the impact of ILEs with modulated composition, such as 0.3 lithium bis(fluoromethanesulfonyl)imide (LiFSI)-0.7 N-butyl-N-methylpyrrolidinium bis(fluoromethanesulfonyl)imide (Pyr₁₄ FSI) and 0.3 LiFSI-0.35 Pyr₁₄ FSI-0.35 N-butyl-N-methylpyrrolidinium bis(trifluoromethanesulfonyl)imide (Pyr₁₄ TFSI), on the interfacial stability of PTNB@Li||PTNB@Li and PTNB@Li||LiNi_0.8<
