ABSTRACT:
A process for producing a WPU-PEO based composite electrolyte is disclosed. The process includes steps of a) providing a polyurethane material as a matrix material; b) dispersing the matrix material in a first solvent and mixing PEO in the same solvent to form a dispersion solution; c) drying the dispersion solution to form a thin composite film of WPU-PEO as a matrix of the polymeric electrolyte; and d) adding a component of an anhydrous liquid electrolyte into the matrix to form the WPU-PEO based composite electrolyte. The fabricated thin film electrolyte has a good conductivity (up to 10.sup.-2 .about.10.sup.-3 S/cm at room temperature) and can be suitably used in cells, e.g. lithium ion batteries, lithium batteries, and electrochromic devices. The feasibility of the use of a mixture of various WPU, cross-linked WPU, and WPU based composite electrolytes in lithium ion batteries, lithium batteries, and electrochromic devices is also disclosed.
