ABSTRACT:
The present invention is related to a process for producing a polyurethane-based polymeric electrolyte including steps of: a) providing a polyurethane material as a matrix material; b) dispersing the matrix material in a first solvent to form a dispersion solution; c) drying the dispersion solution to form a thin film of polyurethane as a matrix of the polymeric electrolyte; and d) adding a component of an organic electrolyte into the matrix to form the polyurethane-based polymeric electrolyte. The present invention is also related to a polyurethane-based polymeric electrolyte including a thin film of a polyurethane serving as a matrix of the polymeric electrolyte; and an organic electrolyte arranged in the matrix for ionic conduction. The fabricated thin film electrolyte has satisfactory conductivity and can be suitably used in cells.
