Complexes formed between lithium salts and low molecular weight (0.5 kgmol-') poly(ethylene glycol) have been investigated by differential scanning calorimetry, 'Li nuclear magnetic resonance (NMR), and complex impedance measurements. 'Li NMR linewidths and hence ionic mobilities are strongly influe
## Abstract The addition of small amounts of crown ethers was observed to enhance the conductivity of the system PEO~20~LiCF~3~SO~3~ (PEO: poly(ethylene oxide)). Optimum conductivity enhancement was observed for the system PEO~20~LiCF~3~SO~3~(crown ether)~0.003~ when 12βcrownβ4 and benzoβ12βcrownβ4
