The present invention relates to a method and a device for collecting a metal and acid from leachate of an electrode material. Provided is a method for collecting a metal and acid from leachate of an electrode material comprising: a step for forming leachate including a metal by mixing an electrode material and an acid solution; and a step for separating an acid solution and a metal inside the leachate through a diffusion dialysis module. Moreover, provided is a device for collecting a metal and acid from leachate of an electrode material comprising: at least one selective anion exchange membrane; a leachate chamber, which is formed in one side of the selective anion exchange membrane, and where leachate including a metal formed by mixing of the electrode material and the acid solution flows; and a water chamber, which is formed in the other side of the selective anion exchange membrane, and where water flows. [Reference numerals] (AA) Distilled water; (BB) Leachate; (CC) Metal collecting solution; (DD) Selective anion exchange membrane; (EE) Collected hydrochloric acid
