摘要
A method for preparing electrode active material slurry including: mixing a conductive agent and a first thickener with a low molecular weight to primarily disperse the mixture; and mixing an active material and a second thickener with a higher molecular weight than the first thickener in the primary dispersion to secondarily disperse the mixture, and an electrochemical capacitor comprising an electrode using electrode active material slurry prepared by the method. It is possible to prepare a low resistance and high capacity electrochemical capacitor by selectively using at least two thickeners with different degrees of polymerization and molecular weights to remarkably improve dispersibility of an active material and a conductive agent. Particularly, it is possible to reduce resistance based on an electrochemical capacitor with the same capacity.
