본 발명은 캐소드; 애노드; 상기 캐소드와 애노드 사이에 개재된 분리막; 상기 캐소드와 애노드 사이에 존재하여 전류를 흐르게 하는 전해질을 포함하며, 상기 캐소드가, 슈도캐패시터 특성을 갖는 촉매 촉매; 및 바인더를 포함하는 수퍼캐패시터 및 이를 포함한 정수용 전기화학장치를 제공한다. 본 발명에 따르면, 캐소드에 슈도캐패시터 특성을 나타내는 물질을 이용한 촉매 반응을 활용하여 기존 EDLC 재료를 사용한 경우에 비하여 용량을 크게 증대할 수 있고, 캐소드에서 진행되는 촉매 반응의 전위를 더 높은 쪽으로 진행하여 시스템의 작동전압을 높여 추가로 용량을 높일 수 있다. 또한 촉매가 담지된 캐소드의 경우, 그 전극 저항이 매우 작아지므로 전체적인 시스템의 저항이 감소되어 출력 특성을 개선하면서 추가로 용량이 높아진다. 또한 전체 시스템의 부피를 1/2 이하로 줄일 수 있고, 사용되는 집전체, 분리막 등의 형성재료를 절반 이하로 줄일 수 있게 되어 제조비용이 절감되는 효과를 얻을 수 있다.
