Abstract: An encapsulated electrode for an electrochemical cell and a method for producing an encapsulated electrode. The encapsulated electrode structure has a first solid-state electrolyte composite (SSE) that has a top surface, a bottom surface, and a peripheral surface. Another layer of the encapsulated electrode structure is the electrode that has a top surface, a bottom surface, and a peripheral surface. Yet another layer of the encapsulated electrode structure is a second SSE that has a top surface, a bottom surface, and a peripheral surface. The first SSE is arranged so as to be attached to the electrode, wherein the bottom surface of the first SSE is attached to the top surface of the electrode. The bottom surface of the electrode is attached to the top surface of the second SSE. Pressure is applied to this stack so that the SSEs deform and encapsulate the electrode.
