摘要: Abstract In the light of polyethylene oxide (PEO) structure, various polymer electrolytes based on tailor-made polyurethane (PU) were prepared and investigated by alternating current (ac) impedance. Equivalent circuits schematic structures proposed to describe conductive behavior these electrolytes. The impedance results show that water-borne (WPU) film, impregnated with propylene carbonate (PC), has a conductivity 2.83×10−5 S cm−1 at 80°C. With addition salt solvent, WPU-based electrolyte exhibits 4.68×10−4 25°C. It is promising use our WPU as for lithium batteries.
