Abstract

The present invention relates to a method for manufacture of a composite separation membrane for a redox flow battery, the method comprising the steps of: coating at least one surface of a porous polymer resin membrane having a weight average molecular weight of 1,000,000 to 10,000,000 with a coating composition including a fluorine- or hydrocarbon-based resin substituted with one or more cation-exchange functional groups; and keeping the coating composition-coated porous polymer resin membrane in a hydrogen peroxide solution, a sulfuric acid solution, or deionized water for 10 minutes or longer.
