Ionic liquid-based quasi-solid-state electrolyte for supercapacitor application

Solvate ionic liquid-derived solid polymer electrolyte with lithium bis(oxalato) borate as a functional additive for solid-state lithium metal batteries

“…The characteristic peaks located at 18.2°, 20.2°, 26.8°, and 40°reect the crystalline a-phase of PVDF-HFP. 32 With the incorporation of the SIL, the absorption peaks at 18.2°and 26.8°nearly disappear and the one at 40°becomes signicantly less intense, indicating that the interaction between SIL and PVDF-HFP disrupts the regular arrangement of the polymer chain and accordingly increases the fraction of the amorphous phase, which is convenient for chain movement and ion migration in the SPE. The addition of LiBOB further causes a slight decline in the overall crystallinity of the SPE.…”

In situ-fabricated quasi-solid polymer electrolytes incorporating an ionic liquid for flexible supercapacitors

“…11–13 However, these are inevitably corrosive, flammable, and toxic, resulting in chemical/thermal instability and a latent safety hazard. Ionic liquids (ILs) 14,15 have emerged as a promising alternative for organic electrolytes by virtue of their high thermal stability, good ionic conductivity and wide electrochemical window. Furthermore, incorporating the IL into a polymer matrix to form a quasi-solid electrolyte (QSE) would be an attractive approach because it could address the liquid leakage issue without sacrificing the intrinsic merits of the ILs, 16 and thus it would hold great application potential for wearable and portable electronic products.…”
