摘要: Ionic transport properties, including ionic conductivity, lithium transference numbers, and diffusion coefficients, of poly(ethylene oxide) 20 LiN(SO 2 CF 3 ) [P(EO) LiBETI] P(EO) LiBETI + x (x = 2, 5 10) wt % filler (7 nm SiO , 12 γ-LiAlO polymer electrolytes prepared by a solvent-free procedure developed at ENEA have been investigated using ac impedance, dc polarization, cyclic voltammetry. Regardless whether or not nanosize fumed particles were added, the conductivity all samples showed similar values trends. Both number coefficient cations decreased slightly addition particles. These results suggest that presence in under very dry conditions has little practical influence on properties.
