Abstract
The invention discloses a polymer electrolyte membrane and a method for preparing the same. The method comprises the steps of: (1) mixing a molecular sieve material, a polymer and a solvent to obtain a slurry; (2) coating the slurry on a base membrane to form a wet membrane; (3) drying the wet membrane to obtain a dry membrane; and (4) immersing the dry membrane in a lithium salt electrolyte solution, and taking out to obtain a polymer electrolyte membrane.
