Falco, Marisa published the artcileUnderstanding the Effect of UV-Induced Cross-Linking on the Physicochemical Properties of Highly Performing PEO/LiTFSI-Based Polymer Electrolytes, Application In Synthesis of 143-24-8, the main research area is UV crosslinking physicochem polyethylene oxide lithium complex polymer electrolyte; magic angle spinning NMR spectroscopy Raman spectra polymer electrolyte.
The authors report a thorough, multitechnique study of the structure and transport properties of a UV-cross-linked polymer electrolyte based on poly(ethylene oxide), tetra(ethylene glycol)dimethyl ether (G4), and lithium bis(trifluoromethane)sulfonimide. The properties of the cross-linked polymer electrolyte are compared to those of a noncross-linked sample of same composition The effect of UV-induced crosslinking on the physico/chem. characteristics is evaluated by x-ray diffraction, DSC, shear rheol., 1H and 7Li magic angle spinning NMR spectroscopy, 19F and 7Li pulsed field gradient stimulated echo NMR analyses, electrochem. impedance spectroscopy, and Fourier transform Raman spectroscopy. Comprehensive anal. confirms that UV-induced crosslinking is an effective technique to suppress the crystallinity of the polymer matrix and reduce ion aggregation, yielding improved Li+ transport number ( > 0.5) and ionic conductivity ( > 0.1 mS/cm) at ambient temperature, by tailoring the structural/morphol. characteristics of the polymer matrix. Finally, the polymer electrolyte allows reversible operation with stable profile for hundreds of cycles upon galvanostatic test at ambient temperature of LiFePO4-based lithium-metal cells, which deliver full capacity at 0.05 or 0.1 C current rate and keep high rate capabilities up to 1C. This enforces the role of UV-induced crosslinking in achieving excellent electrochem. characteristics, exploiting a practical, easy up-scalable process.
