1. A solid electrolyte three-electrode electrochemical test device comprising:
a housing comprising a groove defining a first through hole located at a bottom of the groove;
a working electrode;
a counter electrode;
a reference electrode insulated from the counter electrode;
a first conductive structure, wherein the first conductive structure and the working electrode are stacked with each other, and the working electrode and at least a part of the first conductive structure are located in the first through hole;
a second conductive structure;
a third conductive structure, wherein the third conductive structure is stacked with the reference electrode and insulated from the second conductive structure; and
a solid electrolyte layer, wherein the solid electrolyte layer, the counter electrode, the reference electrode, the second conductive structure and the third conductive structure are located in the groove, and the first conductive structure, the working electrode, the solid electrolyte layer, the counter electrode, and the second conductive structure are sequentially stacked and located coaxially with each other.
