Patent number: 10867755Abstract: A method for manufacturing a capacitive deionization electrode exhibits enhanced ionic material adsorption efficiency. The method includes (a) kneading an electrode active material while adding a solvent to the electrode active material; (b) adding a solvent to the mixture obtained after (a) and stirring the result; and (c) preparing an electrode slurry by adding a binder to the mixture obtained after (b) and stirring the result. According to the method, a problem of a binder blocking electrode pores, which used to occur when using existing methods, is resolved by increasing mixing efficiency of the binder while using an electrode active material having a high specific surface area. A capacitive deionization electrode having very superior ionic material adsorption efficiency may be manufactured using the method.Type: GrantFiled: August 14, 2018Date of Patent: December 15, 2020Assignee: Doosan Heavy Industries Construction Co., LtdInventors: Jang Yong You, Seok Ho Choi, Hyun Sung Choi, Han Joo Kim, Dong Ju Lee
