PEO-Based Network Solid Polymer Electrolyte and Its Electrochemical Properties

摘要

Highly branched network solid polymer electrolytes containing low molecular weight poly(ethylene glycol) dimethyl ether (PEGDMe) were prepared by UV-radiation curing of PEG-based acrylates. The conductivity increased as increasing the content of the PEGDMe. The maximum conductivity was measured to be 8.5X10~(-4)S/cm at 30℃. Reversible plating/stripping of lithium was observed on the stainless, nickel and aluminum electrodes. The electrolyte showed electrochemically stability up to 4.5 versus lithium reference electrode.
