摘要： •New cyanuric chloride based double-core solid hybrid electrolyte is synthesized.•Conductivity of the hybrid electrolyte follows Vogel-Tamman-Fulcher behavior.•Hybrid electrolyte possesses maximum ionic conductivity of 9.5×10−5Scm−1 at 30°C.•PGSE NMR reveals ion pairs and segmental mobility affect Li diffusion coefficient.•Two local environments are identified for Li+ ions in the hybrid electrolyte. A new organic-inorganic solid hybrid electrolyte based on 2,4,6-trichloro-1,3,5-triazine, triblock co-polymer poly(propylene glycol)-block-poly(ethylene glycol)-block-poly(propylene glycol) bis(2-aminopropyl ether), poly(ethylene glycol) diglycidyl ether, and 3-(glycidyloxypropyl)trimethoxysilane doped with LiClO4 salt is synthesized by a sol-gel process. Fourier transform infrared spectroscopy and 13C NMR results reveal the successful synthesis of the organic-inorganic hybrid electrolyte. The conductivity of the hybrid electrolyte follows a VTF (Vogel-Tamman-Fulcher)-like behavior, implying that the diffusion of charge carriers is assisted by the segmental motions of polymer chains. The Li-ion mobility is determined from 7Li static NMR linewidth and diffusion coefficient measurements; both are correlated with their ionic conductivities. The maximum ionic conductivity of 9.5×10−5Scm−1 at 30°C is obtained for the hybrid electrolyte with the [O]/[Li] ratio of 32. The electrochemical stability window of 4V ensures the hybrid electrolyte as a potential candidate for low voltage lithium ion batteries. 出版者： Elsevier Ltd 出版日期： 2014-08-20 出處： Electrochimica acta, 2014-08, Vol.138, p.30-40 版權： 2014 Elsevier Ltd 識別號： ISSN: 0013-4686 識別號： EISSN: 1873-3859 識別號： DOI: 10.1016/j.electacta.2014.06.066
