Abstract
A method for manufacturing a reinforced separator including pretreating a porous support using a first solution including a first ionic polymer and ethanol; and impregnating a second solution including a second ionic polymer and a solvent into the pretreated porous support, wherein a concentration of the first ionic polymer in the first solution is lower than a concentration of the second ionic polymer in the second solution, a reinforced separator manufactured using the same, and a redox flow battery.
