A polymer electrolyte composite membrane is provided to secure stable and high battery capacity in a condition of high temperature and low humidity by using multi-component composite inorganic particles. A method for manufacturing a polymer electrolyte composite membrane comprises the steps of: mixing ammonium carbonate((NH4)2CO3) in zirconyl chloride(ZrOCl2-8H2O) solution to form zirconyl carbonate(ZrOCO3); mixing surfactants with zirconyl carbonate and adding sodium silicate(Na2SiO3) solution gradually to form multi-component composite inorganic particles; preparing a first polymer solution, an then evaporating the first polymer solution under reduced pressure to form a second polymer solution; mixing the inorganic particles in the second polymer solution to form inorganic particles-dispersed polymer solution; casting the inorganic particles-dispersed polymer solution and drying the cast polymer solution for 20-30 hours; and heat-treating the dried polymer solution at 120-200 °C for 30-90 minutes. |
