The present invention relates to a method for preparing a slurry, comprising: a) preparing a slurry by mixing a polymer solution and an electrode active material; b) applying or calendering the slurry on one side or both sides of the substrate to form an active layer; c) coating a mixed solution containing ion exchange resin powder and one or two or more binders selected from linear low density polyethylene, low density polyethylene, polyethylene, ethylene vinyl acetate, polyolefin, polyamide, polyester and polyurethane onto the surface of the active layer Thereby forming an ion selective layer; And d) forming a channel pattern on the surface of the ion selective layer. The present invention also relates to a method for manufacturing a desalting electrode, and a CDI module including the same. The electrostatic desalination electrode manufactured according to the present invention includes a pattern in a channel on an electrode including an ion selective coating layer to automate module assembly and increase mass productivity . In addition, there is an effect of manufacturing a storage type desalination electrode capable of achieving excellent ion adsorption performance and total accumulated charge quantity without a spacer, and is commercially available because it is made in the same shape as a commercial filter product. The present invention is applicable to a cylindrical electrode module that can be used safely even at a water pressure higher than that of a quadrangle module, and it is possible to make various types of modules with high voltage and low current according to the number of desalination electrodes, Can be freely designed. |
