Transitioning to solid-state batteries using polymer electrolytes results in inherently safer devices and can facilitate the use of sodium metal anodes enabling higher energy densities. In this work, solvent-free ternary based on cross-linked polyethylene oxide (PEO), bis(fluorosulfonyl) imide (NaFSI) or bis(trifluoromethanesulfonyl) (NaTFSI) N-butyl-N-methyl-pyrrolidinium-based ionic liquids (...

The development of high-performance solid polymer electrolytes is crucial for producing all-solid-state lithium metal batteries with high safety and energy density. However, the low ionic conductivity their unstable electrolyte/electrode interfaces have hindered widespread utilization. To address these critical challenges, a strong Lewis acid (aluminum fluoride (AlF3)) dual functionality introd...

Solid polymer electrolytes based on lithium bis(trifluoromethanesulfonyl) imide and polymer matrix were extensively studied in the past due to their excellent potential in a broad range of energy related applications. Poly(vinylidene fluoride) (PVDF) and polyethylene oxide (PEO) are among the most examined polymer candidates as solid polymer electrolyte matrix. In this work, we study the effect...

The title compound, 5-[4-[(2-pyridylideneamino)sulfonyl]phenyldiazenyl]salicylic acid, C(18)H(14)N(4)O(5)S, crystallizes as the imide tautomer in the monoclinic space group P2(1)/c. In addition to an intramolecular O-H.O hydrogen bond, intermolecular O-H.O interactions link adjacent molecules into helices, which are connected by pairwise N-H.N interactions into two-dimensional hydrogen-bonded l...

This research focuses on the synthesis and characterization of a piezoelectric (β-CN)APB/ODPA polyimide. The remanent polarization and piezoelectric d31 and g33 coefficients are reported to assess the effect of synthesis variations. Each of the materials exhibits a level of piezoelectricity which increases with temperature. The remanent polarization is retained at temperatures close to the glas...

A simple theoretical model of liquid crystal ͑LC͒ alignment by exposure to linearly polarized ultraviolet ͑UV͒ light is proposed. The model predicts a universal relationship describing the change of the LC anchoring direction with exposure times, and the changes of polarization direction for the case of a double linearly polarized UV exposure process. This relationship is quantitatively confirmed b...
