Synthesis and properties of poly(1,3-dioxolane) in situ quasi-solid-state electrolytes via a rare-earth triflate catalyst

Abstract

We report rare-earth triflate catalyst Sc(OTf)3 for ring-opening polymerization of 1,3-dioxolane in-situ producing quasi-solid-state poly(1,3-dioxolane) electrolyte, which not only demonstrates superior ionic conductivity of 1.07 mS cm-1 at room temperature,...

High-Performance Room Temperature Lithium-Ion Battery Solid Polymer Electrolytes Based on Poly(vinylidene fluoride-co-hexafluoropropylene) Combining Ionic Liquid and Zeolite

“…8 The selection of materials and materials combinations plays a key role in addressing the aforementioned issues. In this context, the combined use of the host polymer matrix and two different doping agents (fillers such as lithium salts, 9 liquid, 10 Nasicon, 11 and/or rare-earth triflate, 12 among others) represents one of the most promising approaches. 13 Regarding the host polymer matrix, a great variety of different materials have been used.…”

Enhanced Electrochemical Performance of Al- and Nb-Codoped LLZO Ceramic Powder and Its Composite Solid Electrolyte

“…Nowadays, we urgently need new forms of nonpolluting or zero-emission energy because environmental pollution and energy crisis are receiving increasing attention. , Lithium-ion batteries (LIBs) are widely used due to their high output voltage, high energy storage density, and environmental benefits. − However, the majority of LIBs use organic liquid electrolytes, which are associated with a range of safety hazards that limit the large-scale application of LIBs in the field of energy storage . These hazards include leakage, explosion, Li dendrite formation, and decomposition at high temperatures.…”

Na superionic conductor-type LiZr2(PO4)3 as a promising solid electrolyte for use in all-solid-state Li metal batteries

“…93 As the GB conductivity is strongly dependent on the process of synthesis, various preparation methods have been applied to reduce the GB and/or interface resistance for LZP and related compounds 38,94 and the other NASICON-type oxides. [95][96][97] The relationships among the composition, crystal structure, presence of the impurity phase, relative density of the sintered body, and ionic conductivity are quite complex. We infer that Low ionic conductivity at low composition y region owes to large GB resistance because of small relative density.…”

“…12 Also, control of sintering degree and stabilization of a-phase, i.e. process optimization 38,[94][95][96][97] would be effective to improve ionic conductivity as well as composition optimization.…”
