TL;DR: A Na-ion solid-state electrolyte, Na3 P0.62 As0.38 S4, is developed with an exceptionally high conductivity and enhanced moisture stability and dual effects of alloying element As (lattice expansion and a weaker AsS bond strength) are responsible for the superior conductivity.
Abstract: A Na-ion solid-state electrolyte, Na3 P0.62 As0.38 S4 , is developed with an exceptionally high conductivity of 1.46 mS cm-1 at 25 °C and enhanced moisture stability. Dual effects of alloying element As (lattice expansion and a weaker AsS bond strength) are responsible for the superior conductivity. Improved moisture stability is regulated by shifting low-energy moisture reactions to high-energy ones due to As.

TL;DR: In this paper, the feasibility of a monolithic, fully inorganic solid state lithium battery is investigated and the reproducibility of the high reported ionic conductivity of Li13Al03Ti17(PO4)3 and the lithium-rich and lithiumpoor stability limits have been investigated.

TL;DR: The phase separation process was enhanced with the increase in the polymer crystallinity and was more significant in the case of the homopolymers as mentioned in this paper, leading to non- or low-porous membranes when the phase separation remained in its early stage or to highly porous membranes when it was mostly achieved.

TL;DR: Pyrrolidinium based PILs have a relatively low cost, a low toxicity and exhibit a large electrochemical window as compared to other protic ionic liquids (up 3 V), and are good or superionic liquids and shows extremely fragility.
Abstract: New pyrrolidinium-cation-based protic acid ionic liquids (PILs) were prepared through a simple and atom-economic neutralization reactions between pyrrolidine and Bronsted acids, HX, where X is NO 3 (-), HSO 4 (-), HCOO (-), CH 3COO (-) or CF 3COO (-) and CH 3(CH 2) 6COO (-). The thermal properties, densities, electrochemical windows, temperature dependency of dynamic viscosity and ionic conductivity were measured for these PILs. All protonated pyrrolidinium salts studied here were liquid at room temperature and possess a high ionic conductivity (up to 56 mS cm (-1)) at room temperature. Pyrrolidinium based PILs have a relatively low cost, a low toxicity and exhibit a large electrochemical window as compared to other protic ionic liquids (up 3 V). Obtained results allow us to classify them according to a classical Walden diagram and to determinate their "Fragility". Pyrrolidinium based PILs are good or superionic liquids and shows extremely fragility. They have wide applicable perspectives for fuel cell devices, thermal transfer fluids, and acid-catalyzed reaction media as replacements of conventional inorganic acids.
