Lattice and ion dynamics in gel electrolytes based on poly(acrylonitrile) by6Li-7Li NMR
- 11 Downloads
Two composite gel electrolytes prepared from mixtures of poly(acrylonitrile) (PAN), propylene carbonate (PC), ethylene carbonate (EC) and LiClO4 have been studied with differential scanning calorimetry (DSC) and7Li-6Li NMR. The data allow estimation of ionic conductivities, local (short range) diffusivities, and lattice dynamics. Furthermore, they point to an unexpected behavior of the Li-rich sample that hints to a complex LiClO4-PAN phase diagram.
