Zusammenfassung:The present invention relates to an electrochemical device and a manufacturing method thereof. The electrochemical device of the present invention solves a safety problem of a fire risk of a conventional liquid electrolyte, and explosion when the electrolyte is leaked and exposed to external air and moisture, maximizes the efficiency of a device by adding a carbon material having a large specific surface area, and maintains a flexible form by mixing a polymer additive with negative and positive electrodes, thereby being applied to various fields. In addition, the electrochemical device of the present invention can be simply manufactured by a one-step process through hot pressing, such that process costs and time can be significantly reduced. 본 발명은 전기화학소자 및 이의 제조방법에 관한 것으로, 본 발명에 따른 전기화학소자는, 기존의 액체 전해질의 화재 위험, 전해질 누출 및 외기나 습기에 노출 시 폭발 등이 안전성 문제를 해결하였고, 비표면적이 큰 탄소재를 첨가하여 소자의 효율을 극대화시켰고, 음극 및 양극에 폴리머 첨가제를 혼합하여 플렉서블(flexible)한 형태를 유지하여 다양한 분야에 적용할 수 있다. 또한, 열간 압착을 통해 원스텝(one step) 공정으로 간단하게 제조할 수 있어, 공정 비용 내지 시간을 현저히 줄일 수 있다.
