Conductivity of poly(ethylene oxide)/silica composite films containing lithium trifluorosulphonate

Conductivity of lithium triflate dissolved in silica/PEO composites is reported. The amount of silica added to the films varies between 7% and 24%, high and low molar mass PEO samples are used as co-composite materials. Measurements indicate good conductivity coupled with good physical properties over a range of temperatures.
