The present invention relates to an electrochemical device and a manufacturing method thereof. More specifically, the present invention relates to an electrochemical device and a manufacturing method thereof, wherein in an electrode assembly consisting of an anode, a separator, and a cathode, the anode, the separator, and the cathode are each composed of a combination of a solid electrolyte and a gel polymer electrolyte, and wherein at least one or more selected from a first electrolyte, a second electrolyte, and a third electrolyte of the gel polymer electrolyte has a different composition. In addition, since the electrochemical device of the present invention includes an electrolyte having different ion conductivities in at least one or more of the anode, the separator, and the cathode, it is possible to provide an optimized ion flow to each electrode and separator, and thus, the present invention has a more advantageous effect on improving lifespan characteristics and safety of the electrochemical device. |
