Recent progress in solid polymer electrolytes with various dimensional fillers: a review

Solid hybrid electrolytes based on conductive oxides and polymer electrolytes for all-solid-lithium batteries

“…Various methods have been employed to fabricate 3D nanoporous materials, including electrospinning, 3D printing, and sacrificial templates. 174 Fu et al introduced a 3D lithium-ion-conducting ceramic network based on a garnet-type Li 6.4 La 3 Zr 2 Al 0.2 O 12 (LLZO) as a continuous Li + transfer pathway within a PEO-based hybrid electrolyte. 166 The ceramic network was fabricated using electrospinning and high-temperature sintering techniques, as depicted in Fig.…”

Well‐Dispersed Polydopamine In Situ Coated Lithium Montmorillonite Nanofillers Composite Polyethylene Oxide‐Based Solid Electrolyte for All‐Solid‐State Lithium Batteries

“…These limitations can impair the battery's output performance and cycle life. [20,21] With efforts being centered on enhancing the overall performance of PEO-based solid electrolytes, various modification methods for PEO-based solid electrolytes are striving into practice, including cross-linking, [22] copolymerization, [23] blending, [24] and adding nanoinorganic fillers [25] for the last 40 years. Among the various methods, incorporating nanoinorganic fillers has emerged as a feasible approach while it not simply enhancing the mechanical and electrochemical properties of the electrolytes but convenient to prepare.…”

Suppression of Dehydrofluorination Reactions of a Li0.33La0.557TiO3-Nanofiber-Dispersed Poly(vinylidene fluoride-co-hexafluoropropylene) Electrolyte for Quasi-Solid-State Lithium-Metal Batteries by a Fluorine-Rich Succinonitrile Interlayer

“…Among various Li + -conducting ISE fillers, perovskite-structure Li 0.33 La 0.557 TiO 3 (LLTO) shows high Li + conductivity (up to 10 –3 S cm –1 at room temperature), excellent chemical and thermal stability under air, and great environmental friendliness. − Recently, the incorporation of LLTO into an SPE has been attempted by several groups. ,,,, However, using conventional LLTO particles often does not effectively enhance the Li + conductivity of a CSE. The morphology of an ISE filler plays a crucial role in CSE conductivity. − One-dimensional nanofibrous fillers are favorable because they can provide long-range ion transport channels and their high surface area improves the interaction with the polymer phase. ,− Compared to randomly dispersed ISE particles, a one-dimensional structure with a high aspect ratio provides faster Li + conducting pathways within a CSE . It is noted that Li + transport cross ISE particles or the ISE/polymer interface is rather resistive due to the existence of space-charge layers. , Continuous one-dimensional ISE fibers can adequately reduce this kind of junction resistance, increasing Li + conductivity.…”
