  • Publication number: 20220073381
    Abstract: Proposed are a manufacturing method of a composite capacitive desalination electrode which can increase the desalination efficiency and as a new structure with more excellent mechanical and chemical resistance, and a composite capacitive desalination electrode and assembly. The manufacturing method includes the following steps: a) forming a composite microporous membrane by forming an ion exchange resin layer on a surface of the microporous membrane; and b) forming the composite microporous membrane prepared in the step a) on both sides of an electrode sheet, thereby producing a first unit including the composite microporous membrane and the electrode sheet. The steps are performed in a single process line by an in-line continuous process.
