MANUFACTURING METHOD OF POROUS ACTIVATED CARBON AND NON-POROUS CARBON MATERIAL COMPOSITE ELECTRODE FOR CAPACITIVE DEIONIZATION

摘要

PURPOSE: A method for manufacturing a composite electrode for capacitive deionization using porous activated carbon and non-porous carbon materials is provided to improve the efficiency of ion removal from a solution containing various ion, static-electrical adsorption/desorption, and the durability of the electrode. CONSTITUTION: A method for manufacturing a composite electrode for capacitive deionization using porous activated carbon and non-porous carbon materials is as follows. Porous activated carbon and non-porous carbon materials are dispersed in solvent(S10). The solvent contained in the porous activated carbon and non-porous carbon materials is evaporated(S20). The dried powder of the porous activated carbon and non-porous carbon materials are mixed with a physical method in order to improve the dispersibility(S30). The mixed powder is mixed with an adhesive, polytetrafluoroethylene suspension, the mixed slurry is formed into a sheet to be laminated on carbon foil, and the laminate is pressed to form an electrode(S40). The electrode is dried in a vacuum oven(S50).
