A combination of ac impedance methods and 3-electrode cells were employed to study separately the V6O13 and lithium interface with, solid, high molecular weight PEO (5 × 106), and liquid, methoxy end-caped low molecular weight PEO (222). Surface layers appear to be present on both electrodes. Generally both the lithium and V6O13 interfacial impedances develop until they are significantly larger than the bulk electrolyte resistance. © 1989.
