摘要
The origin of the ionic conductivity enhancement in polymer electrolytes that occurs on adding inorganic oxide powders was explored by H-1 and Li-7 nuclear magnetic resonance. Ionic and molecular self-diffusion coefficients determined by pulsed field gradient spin-echo measurements demonstrate that lithium ionic diffusivity is enhanced in the composites, but this enhancement is not attributed to polymer segmental mobility. Two different systems were investigated: a high-molecular-mass poly(ethylene oxide)-LiClO4 complex with nanoscale TiO2; and a low-molecular-mass poly(ethylene glycol)-LiClO4 solution with Al2O3 In the latter case the effect of varying the alumina surface acidity or basicity was considered.
