摘要：

A new family of polymer electrolytes based on a poly(allyl glycidyl ether) (PAGE) platform has been developed that overcomes many of the limitations of poly(ethylene oxide) (PEO) for battery electrolyte applications. PAGE was shown to have peak conductivities at [O]/[Li] = 16, with sigma > 3 X 10(-5) S/cm at 25 degrees C and sigma > 5 x 10(-4) S/cm at 80 degrees C. Below 60 degrees C, PAGE has a conductivity that is 10-100 times higher than that of PEO at equivalent salt concentrations with this disparity in conductivities between PAGE and PEO increasing with decreasing temperature. In addition, the synthetic versatility of allyl glycidyl ether as a building block is demonstrated by the preparation and evaluation of various AGE-EO macromolecular architectures that show superior performance to both PAGE and PEO.
