ABSTRACT:
The present invention discloses a fabrication method of a basic polymer electrolyte film of blended polyvinyl alcohol and quaternary amine, wherein hydrophilic polyvinyl alcohol and quaternary amine are separately dissolved in a polar organic solvent, and then, the solutions are blended to obtain a glutinous polymeric solution; the glutinous polymeric solution is baked to form a film, and then, the film is soaked in an alkali hydroxide solution to obtain a basic electrolyte-containing solid-state polymer electrolyte film. The basic polymer electrolyte film of the present invention has the characteristics of superior chemical stability, high mechanical strength and high ionic conductivity. When the present invention applies to a zinc-air battery, the utilization rate of zinc is promoted. The basic polymer electrolyte film of the present invention can be widely used in various energy storage systems, such as alkaline battery systems, alkaline fuel cells and capacitors.
