Abstract
The present disclosure relates to a multilayer reinforced composite electrolyte membrane and a method for manufacturing the same. The multilayer reinforced composite electrolyte membrane according to the present disclosure has sufficient mechanical properties and improved membrane resistance at the same time since a porous support is impregnated in an ionomer and it is stacked in a multilayer structure. Furthermore, since the composite electrolyte membrane has no wrinkles and cracks due to excellent dimensional stability, it can improve the electrochemical properties of batteries.
