Abstract
A WPU(PEG)-WPU(PTMG)-PEO triple-polymer based composite electrolyte is disclosed. The electrolyte includes a thin composite film and an anhydrous liquid electrolyte within the thin film. The thin film is composed of WPU(PTMG) serving as a support, PEO serving as an adsorbent of the liquid electrolytes, and WPU(PEG) serving as a compatibility promoter. On the other hand, the anhydrous liquid electrolyte is used for ionic conduction. The resulting thin film electrolyte has a good conductivity (up to 10.sup.-2 .about.10.sup.-3 S/cm at room temperature), especially within a compositional range of 0.about.75 wt. % WPU(PEG), 0.about.45 wt. % WPU(PTMG), and 20.about.95 wt. % PEO. A WPU(PEG)-WPU(PTMG)-PEO based composite electrolyte is adapted to be used in lithium ion batteries, lithium batteries, and electrochromic devices.
